Oh, and PCI-X GeForces are available on the market? I guess I'll have
to look around again :-)

Hmmm... AFAIUI, the PCI-X controller on the Opteron is supported, how
good the support is, no idea. The same goes for the AGP part. Some
PCI-X stuff was contributed by HP, for their very cool Alpha system
(which is supposed to run Linux, too) and their Itanium systems (all
these use the ZX1 chipset). But poking around the K8/AMD64 drivers, I
don't see any explicit mention of PCI-X and I was never sure what that
meant...
From the kernel logs I got (AGP system), I got the impression the thing
was having trouble inside the interrupt handler, but blind guesses at
the problem didn't have much success.

I general they read bug reports, act on them, but the release schedule
is rather slow. On their driver download page you'll find a link to a
support forum where one of their employees hangs around answering
questions. If you give the guy enough info for them to reproduce the
problem, they usually do something about it, but as I said, you have to
have a ton of patience. It's far from perfect, but since so many
people bought into it, I don't really think this will ever change.
Thanks for the info,
Marcelo
