I noticed something interesting about kernel 3.6.5-rt14. spinymouse@qrc:~$ uname -a Linux qrc 3.5.0-17-lowlatency #18-Ubuntu SMP PREEMPT Tue Oct 9 20:04:43 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

However, the kernel does switch to another IRQ for the graphics, for all other kernels on different distros, the graphics always gets IRQ18, also if I switch the integrated ATI with a Nvidia.
