[LAU] rt prio with kernel 3.x, issue to use the vesa driver

That for a shared IRQ the graphics will become an unwanted high prio
doesn't happen with a kernel 2.6.31-rt19 + NVIDIA 195.36.15 on Suse 11.2
on my machine.
As already reported, it also doesn't happen with the kernels
3.0.23-avl-7-pae (threadirqs) and 3.0.23-rt40 on current AV Linux, where
still the nv driver is available and used on my machine.
IIUC it's definitive related to the kernel, I anyway will test the vesa
driver with Ubuntu Studio Precise, but can' get it working.
I modified the xorg.conf I use with the nvida driver, startup ends with
tty, no X. Does anybody notice what I might have missed?

PS: If there won't be an rtirq script able to handle it or any other way
to do it, I hadn't time to test until now, I'll simply will use a kernel
<= 3.0 instead > 3.0.
