Hmm, this looks OK.

I've fixed the problem in my original patch. I've attached the new version.
It works fine with ivtv, the problems with reading the eeprom are now
fixed. Please test and if it still doesn't work then I'll have to install
my bttv card in my PC and test again. But that will be tomorrow evening.

BTW, it would be nice if you can confirm that everything is working fine
if you compile bttv as a module. Just to make sure that this is related
to the in-kernel build. The other person who had this problem (and who
had a very similar card) said that it was working after moving that line
in the Makefile.
