OK, so what does the following mean:

   0: 287954 IO-APIC-edge timer
   1: 10 IO-APIC-edge i8042
   8: 2 IO-APIC-edge rtc0
   9: 3568 IO-APIC-fasteoi acpi
  12: 122 IO-APIC-edge i8042
  14: 12851 IO-APIC-edge ide0
  15: 48253 IO-APIC-edge ide1
  16: 1 IO-APIC-fasteoi uhci_hcd:usb1, yenta
  17: 25387 IO-APIC-fasteoi Intel 82801DB-ICH4, Intel
                                     82801DB-ICH4 Modem
  18: 0 IO-APIC-fasteoi uhci_hcd:usb3
  19: 21569 IO-APIC-fasteoi uhci_hcd:usb2
  20: 2 IO-APIC-fasteoi ohci1394
  21: 1957 IO-APIC-fasteoi eth1
  22: 6207 IO-APIC-fasteoi ath
  23: 192291 IO-APIC-fasteoi ehci_hcd:usb4

If I have a soft synth running, big updates to the screen display will
make it start and stop. But I'm not running an RT kernel here.
