hmm ... it's known that the composite extension doesn't work well with xinerama,
but as far as I can tell, xinerama is not enabled in your setup, so it should be fine.
Maybe composite also doesn't work stable with a multi-screen setup.
You may try disabling several extension, just to see at which point things
start to get stable:
Option "RENDER" "False"
Option "DAMAGE" "False"
Option "Composite" "False"
Also, did you yet tried some kernel boot options that often helped in the past,
like: noapic noacpi maxcpus=1
Concerning the "official" bug report: the announcement of earlier driver
versions suggested to send a mail to "linux-bugs at nvidia.com":
Maybe that still works.
As for purchasing support, I guess the only "official" way is to contact
customer care (I guess you could file your bug report there, as well):
(Then click "NVIDIA Customer Care")
With 2000 FX580 laying around, I would expect you get at least some
little attention :-)
