fine on an RT kernel. they provide a stub/wrapper that is recompiled as
part of driver installation. hence, the actual driver interface is
always built against your actual kernel, but it just proxies into the
real code. obviously, they have to have a driver for a kernel close to
the one that you applied the RT patch to, but this so far has not been a
problem.
One might get this impression when not installing kernel debugging
messages with RT kernels. If one does, one sees dmesg output plastered
with BUG's. Especially by modprobe when loading the nvidia module. And
there's of course these "nvidia: uh oh, sleeping while holding a lock!!"
(paraphrased) messages, too.
If you don't make backups regularly, don't use the nvidia drivers
together with -rt kernels.
This situation might be different for different kernel versions, but it
is a _real_ problem.
I always build two kernels. One with -rt and one w/o. The latter is for
gaming (naturally i have to xorg.conf's too)..
