While we're at it, I tried to backtrace the PCI Vendor ID:s for the 
individual machine quirks we have, and came up with the following list:

8086:27d8 (rev 01) (Intel Corporation N10/ICH 7 Family) - appeared twice
8086:284b (rev 02) (Intel Corporation 82801H (ICH8 Family))
8086:293e (rev 03) (Intel Corporation 82801I (ICH9 Family))
8086:3b56 (rev 05) (Intel Corporation 5 Series/3400 Series)

If you don't mind doing some more lurking, do you think any of the above 
chips should be tweaked to use LPIB position fix method for the entire 
chip, and not just the individual machine?

(For the sake of completeness, 1106:3288 (rev 10) (VIA Technologies, 
Inc. VT1708/A [Azalia HDAC]) also appeared three times.)
