As long as every distribution does the same ;). If an fdi file needed on ubuntu
would not be needed on fedora, that would be very confusing. The problem is that
quirks needed for suspend to work - change over time. For every kernel/driver
version they have to be retested.
As an example.. the macbook pro(1. gen) quirk (vbe_post) is actually harmfull
for fglrx 8.03 + 2.6.24-12. Ofcourse this is with fglrx... so who cares ;).

I have no clever solutions, just wanted to note that quirks are not constant
over time. I think this makes it very hard to keep a database of correct quirks.
I'm probably wrong :)
