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 
shines.
