Loads fine if I remove the cx88 rpm. The cx88 driver loads fine with or
without ivtv
Looks like the culprit is
/lib/modules/2.4.22-1.2163.nptl_34.rhfc1.at/updates/drivers/video/media/tuner.o
If I remove this and depmod -a, all is fine in ivtv land. The cx8800
module even loads without it. I get tuner.o from
/lib/modules/2.4.22-1.2163.nptl_34.rhfc1.at/kernel/drivers/media/video/tuner.o
I am guessing this is the same for you bttv users.
