I'm happily running 2.6.4 on KnoppMyth (FWIW 2.6.6 doesn't work for me)
have been for months :)
As of last weekend it's been sata only.
I needed to grub --recheck but that was the main issue.

Onboard via - a KT600 (see my mythtv.info page for more details)

Well I found it pretty straightforward. OTOH I've done that kind of
thing a lot. (and I cheated by installing to pata and then migrating to
sata)

Hmm, the nice think about KnoppMyth is you have an nice live OS booted
from CD :)
You can even compile a new kernel (memory dependent!)
I wonder if your problem was not passing root=/dev/hde1 or
root=/dev/sda1 to the kernel? (depending on ide/libata)

I've said (a few times) that I think 2.6 is better than 2.4 for ivtv.
(just based on problems reported with 2.4 that I've never seen so YMMV)

Dex recently said he was going to start some writeups of moving to 2.6
but he's not started yet.
See here though:

and I'll help with any questions.

PS and before anyone asks - no you don't need sata - and you don't get
much benefit from it :)
