I moved this card from a x86 box to this 64x2 AM2 box and the following 
files have the same contents. udev the same as on the x86 box. This is 
definitely a KWorld/VStream XPert DVB-T card which I had working for 
over one year at least. Kernel is 2.6.22-rc3, same problem with 
2.6.22-rc2-git7. I haven't checked it in a few weeks on the x86 box, but 
it was OK on earlier 2.6.22-rc kernels.

I added this to modprobe.conf.local to get the card recognised.
