I don't think Axel builds kernel module rpms for that kernel anymore, 
but I could be mistaken.

Actually, you MUST get something newer than 0.6.6 to use the PVR-x50's 
remote. Support isn't there until the 0.7 pre releases.

No, you really only need your kernel config file in place.

His kernel is 2.4.20-8, which is the kernel shipped on the Red Hat 
Linux 9 isos (non-boxed version; that had 2.4.20-6 kernels). He's using 
that because it allows him to use VIA's cle266 binary drivers. The 
corresponding kernel-source rpm should be installed from the discs.

Copying /usr/src/linux-2.4.20-8/configs/kernel-2.4.20.<arch>.config to 
/usr/src/linux-2.4/.config is all that is absolutely necessary. I know, 
because I've done it. ;-)

Yeah, I don't think that package gets built at all. Processor and time 
constraints, since Axel builds soooo many kernels and kernel modules 
already...

No. =)

Grab the lirc-0.7.0pre2 source and compile it against your kernel. My 
doc has a brief little section on what is necessary.

No.

Heh, yeah, that's an ugly one... apt-get really hides how twisted those 
deps are (I remember installing all those deps by hand myself quite 
some time ago -- ouch).
