Subject: Patch to make VIA sata board bootable again.

Hello

The quirks.c update that went into 2.6.16.17 made an VIA machine here 
non bootable from an sata drive (via_sata), the error is:

"ATA1 qc timout"
"Failed to set xfermode".

And later kernel panic becouse no sata disk was found.
I tracked it down to the quirk update in 2.6.16.17. Below is a patch 
against 2.6.17.11 that reverses the uppdate and makse the system 
bootable again.

Another option is to find out the PCI_DEVICE_ID_VIA for the motherboard 
in question but I could not get that info. Dose someone have an idea how 
to find that info? then I can provide an patch that adds the right 
PCI_DEVICE_ID_VIA for my motherboard.
