Default new rtirq release

The truth is, that it's not completely solved, there's at least the need
to switch the config script when using different kernel versions.

RTIRQ STILL IS
rtirq - Revision 7, resp. $ wget [snip] --2012-05-05 03:09:00--

First the drawback when using 1 config for both kernels, then
3.2.0-23-lowlatency with good prios and then 3.0.30 (lowlatency) with
good prios. Using nvidia-current-295.40 with both kernels.

Rebooting seems to be important, stop and start rtirq seems not to work.
