That's understandable; Not having any control nor insignt into the
driver's inner workings makes things tough to support.

However, what I was really trying to address with my patch was the
regression from when I was running Ubuntu 7.10 and suspend worked 100%.

The check for any model number starting with 6460 assumes that an intel
chipset is used, but that's not the case: my 646066U has an nvidia
quadro 140m. So, maybe you won't directly support binary drivers, but
the assumption that all 6460* T61 models have an intel card and are fine
with s3_bios is a little bit too far-reaching...
