Wow!  I'll take two helpings of that please since I have a 2800XP 
here :)

[root at coyote init.d]# cat /proc/interrupts
           CPU0
  5:     187328          XT-PIC  ehci_hcd, radeon at pci:0000:02:00.0

[root at coyote init.d]# glxgears
47 frames in 5.0 seconds =  9.400 FPS
50 frames in 5.0 seconds = 10.000 FPS
Broken pipe
[root at coyote init.d]# cat /proc/interrupts
           CPU0
  5:     189182          XT-PIC  ehci_hcd, radeon at pci:0000:02:00.0

From the diff between IRQ5 before & after, there were a lot more 
interrupts than frames rendered. 189182-187328=1854 & there was no 
traffic on the usb ports that I know of.

Q?  How do I put the video card on its own IRQ? 10 isn't in use here 
with this bios set for autoconfig.
