Uhm, the cables are 40 vs 80 conductors :)

Anyhow I'm pretty sure this problem is because of the buggy VIA 82C686B
southbridge and a matching BIOS that doesn't setup the right workarounds
for it to function like intended. Clearly the tweaks we install are not
enough on this baby.

Recommended action is to update (well sometimes downgrade) the BIOS to
a version that makes things work...
