It seems necessary to get some ways to load dvb modules in fixed order, or a 
least number the dvb adapters consistently.
1. add option like alsa: index=#
2. just load modules in correct order
3. Do some udev rules like it is done for network devices to make them 
persistent based on mac-addr.

Well, it is the ebuild udev-113-r2, and this code just got added 3 days ago. I 
doubt that other distos use that, as I wrote this on my own, and did not see 
similar stuff otherwhere up to now.
It will not be stable before at least one month.
