I installed the kernel packages Luis uploaded (cf. comment #7). I confirm what Travis reports about it (comment #10): This custom kernel works with the current nvidia driver. But:

1. Synaptic complains about a failed post-installation script. This is most probably a minor issue.

2. I have compared this custom kernel to the 2.6.28-3-rt kernel that comes with ubuntu studio (both with the proprietary nvidia driver disabled). Jack processor load with the custom kernel is *much* higher than with the rt-3-kernel. Identical Jack cofig, identical setup (Ardour routed through JAMin):
- rt-3-kernel processor load: 14%
- Luis' custom kernel: 54% (!)

Either the rt-3-kernel is strongly optimized, or Luis kernel is in some way infefficient.
However, Luis has abviously solved the problem with the nvidia driver.
Luis, can you comment on what you had to do to compile the ciustom kernel?
