Same here.
We actually had the graphics card and the sound card on IRQ 5 for a long
time with no apparent problems.
(I attributed it to using Xvesa, and the processor speed.)

We finally pulled the card out and moved it around to get it on IRQ 7, but
have not noticed any change in performance - didn't seem to matter at all.
