I just built a new system based on Jarod's specs and
2.6.18-1.2798.fc6.i686 loaded those drivers just fine. Then I updated
just the kernel to 2.6.20-1.2925.fc6.i686 and cx88-dvb and blackbird
immediately stopped loading. Looking at the new cx8802 and cx88-dvb
modules, they have the same pattern of bogus aliases that the V4L
modules had. I've gotta think the V4L silliness has now infected the
new kernel and that's why we're hearing it will be fixed in 2.6.21.
From what I've read, I believe the driver loading is controlled by the
associations in modules.alias and those associations come from the alias
fields in the modules being matched to the cards. Kudzu comes along
after the fact and reveals what got matched to what, and it can control
things by stuffing lines in modprobe.conf for the next boot.
To Dennis, yes modprobe cx88-dvb does get everything back in shape. The
Fedora kernel is behaving exactly like the live CD did. And after a 15
minute install, upgrading the rest of the system took 2 hours and 20
minutes (298 files, 509MB) on a 3Mb DSL line. That's where MythDora
