No, it's not.

Here's the order of interrupt priority on a non-APIC machine:

0, 1, 8, 9, 10, 11, 12, 13, 14, 15, 3, 4, 5, 6, 7

0 is the highest priority
7 is the lowest priority

5 is way down on the list, just about everything else has priority
over it.  I have a Delta 1010, and rarely run into xruns.  My IRQs are:

xtc:~% cat /proc/interrupts
           CPU0       
  0: 2947127195          XT-PIC  timer
  1:     796739          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  8:          1          XT-PIC  rtc
  9:   12759493          XT-PIC  ICE1712
 10:  195005487          XT-PIC  eth0, nvidia
 12:   13312679          XT-PIC  PS/2 Mouse
 14:     180887          XT-PIC  ide0
 15:    1987385          XT-PIC  ide1

I've turned off the USB ports on my machine as well as acpi, which handles
OS-directed configuration and power management.
