I'd like to raise motivation a lot because most MB sold here (central=20
Europe) are Nforce4 with Athlon64x2 at the moment. It would be nice=20
from vendors if they support OSS developers more, as it's their=20
interest to have good drivers.

=46or the moment, I'd recommend *against* using Nforce4 because of that=20
problems we had (and that caused us a lot of unpaid repairing work).=20
Hopefully NV does something quick to resolve the remaining issues,=20
especially as the 4GB "border" is hit more and more often.
