Oh, there is one other possibility: are you using kernel 2.6.15 with the
kernel-supplied cx25840 module? In that case you much replace it with
the cx24850 from ivtv. The kernel option to enable the register setting
support never made it into 2.6.15 (it's in 2.6.16 though) so you cannot
use the -g option with the kernel's cx25840.
I hope that's it, otherwise I'm running out of ideas :-)
