the kernel i use from the KXstudio ppa works with my nvidia hardware and the
proprietary driver. i use kernel-realtime from the
https://launchpad.net/~kxstudio-team/+archive/kernel PPA. again, i cant say
how this will work with your graphics hardware, but in ubuntu 10.04 with my
presonus firepod firewire device i can run stable at around 5ms latency.
*this is with no xruns.
