Hey, thanks for the script.. the kernel is built, and I've booted using it,
but I didn't test it yet. The nvidia driver does not work, but if I could
set my screen resolution correctly, that would be enough for me. I then
could switch between kernels for audio and graphic, 3D work. I hope I won't
have to re-enable the nvidia driver each time I boot into the generic
kernel, and disable it again when I boot into the realtime kernel.

The resolution of my screen is not listed in the tool provided for modifying
the resolution. It should be 1680 x 1050 at 109 Hz, but it's limited to 1400
x 1050 at 56 Hz.

Ralf, you mentioned the 2.6.39 kernel. You meant the real time features will
be included in this generic kernel? That would be wonderfull, no need to
have specialised kernels for it anymore, and with nvidia driver capabilities
:-D. I hope will be released in a repository soon.
