Somebody's quoting is making it look as if I'm the OP. I am not, and my
stuff is running just fine.
But unless I missed the memo, the OP still has a problem.
FWIW, the nvidia driver is a profane word in my machine control world. It
doesn't like to share its toys, locking out the irq's for hundreds of
milliseconds at a time, when the cpu is expected to check the machines
status at millisecond intervals to see if its tripped a limit switch
The nouveau driver doesn't do that. And its fast enough to draw a
backplot of the machines motion in close to realtime.
The ATI drivers are better, but they also do the irq lockouts for too
long, so the "better" is still relative, and still not good enough for
good, 100% safe, machine control. ATM, my x86 boxes are all running the
intel i915 drivers, which seem to be doing things well.

Which somehow seem to have vanished from the used market.

Gonna need it Hans, I made the mistake of looking out the front door at
my wheelchair ramp construction area this morning, finding 1/4" snow on
all my nice new lumber. And I still have one, maybe two long days work
demolishing the deck where the ramp will go. Taking screws out with a
big prybar. It would be nice if they'd just unscrew, but they've been
there 15+ years. Takeing 20 calendars off my pile of discards would help
too as I'm not the man I once was, even once... Sigh.
