Quick data points with Finnish YLE DVB subtitles, using a dxr3:
1.7.22: everything works (never tried versions between here, because I was stuck with a 2.6 kernel back then) 1.7.25: subtitles are almost black and thus illegible 1.7.26: same thing 1.7.27: colours OK, but during live programming, maybe one of every 20 subtitles shows at all, and are about half the correct size. Same thing when viewing recordings made with this version - when I replay old recordings, all subtitles seem to get displayed.
vdr-dxr3-plugin version 0.2.13 from here: http://projects.vdr-developer.org/projects/plg-dxr3/files
em8300 drivers from here (cloned on March 17th, I think): hg clone http://dxr3.hg.sourceforge.net:8000/hgroot/dxr3/em8300 dxr3
System Ubuntu Oneiric, kernel 3.0.0-17 from Ubuntu sources (but recompiled by myself, because those nice folks at Ubuntu had to turn OSS support off in the kernel, preventing the em8300 drivers from working)

I remember using alsa with em8300 already years ago? Was I dreaming? :)
Perhaps you were using ALSA years ago. As far as I understand, the audio layer options in the em8300 drivers are a no-op nowadays and it will always try to use register_sound_dsp() etc and these will fail without OSS support in the kernel.
Or what do I know, every time I upgrade my VDR installation I spend an hour googling dead links and obscure mailing list archives for what the "current" version of the drivers might be, and then another half an hour finding out how & where to download it. Perhaps there is a recent ALSA-only em8300 driver somewhere...
OSS support was gone in Ubuntu Maverick: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/579300
...and I had to do system upgrades Lucid -> Maverick -> Natty -> Oneiric to get a 3.0 kernel so I could try the newer VDRs, and only then found out the em8300 drivers wouldn't load.
Anyway, until there's a proper fix for the subtitles, I'm going to stay at .22 because it simply works for me, and the new style YLE subtitles actually look a lot better with the dxr3. The old subtitles always were fat and ugly compared to how they looked on deviced that had a proper alpha channel, or whatever the culprit with dxr3 is.

So yeah, there shouldn't be need for OSS support in the kernel.

I googled your quote. Apparently it is from some Fedora release note from 2007 and I don't think it will help me a bit with an Ubuntu kernel from 2012, as the driver project has been forked, patched and merged a number of times after that.
I'll gladly receive a current, relevant reference that will tell me how to use the em8300 drivers on current Ubuntu without recompiling the kernel. It takes 18(!) hours of CPU time on my VDR box.
Also, can we try and discuss the subtitling problem as well?

Yep, it was from Fedora. You could always check the Fedora src.rpm for any extra patches they might have there..
I think your best bet is to post to dxr3-devel@lists.sourceforge.net mailinglist, I think all (most) the em8300 developers are there..

Sorry I can't really help with that..

Well, I googled a bit more, and it seems the actual problem is in dxr3-plugin, not the drivers. The plugin is only able to use OSS (as of Dec.2008, anyway). I'm not willing to waste time fighting with semi-functional compatibility layers, so I'll just keep using my own kernel. Next time I'll configure out all the unneeded junk before compiling, though :D

Why don't you cross-compile your kernel on a faster computer ?
Because I don't really have any with a suitable distribution installed. And once it takes more than 15 minutes, it's pretty much the same difference if it's two or six or ten hours... I'm not going to compile it again until I'm forced to. I ran 2.6.15 from 2006 until last October!
