interesting. I'm also interested in decreasing latencies for my USB 
cards, and my interrupts read as follows:

   0:    1620247          XT-PIC  timer
  1:       4669          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  8:          2          XT-PIC  rtc
 11:    1636542          XT-PIC  Intel 82801CA-ICH3, Intel 82801CA-ICH3 
Modem, uhci_hcd:usb1, uhci_hcd:usb2,eth0, yenta, yenta, ohci1394, 
nvidia
 12:        114          XT-PIC  i8042
 14:      52911          XT-PIC  ide0
NMI:          0
LOC:          0
ERR:          0
MIS:          0

11 really seems to be overcrowded, so I wonder if I could use another 
IRQ for the USB bus. Unfortunately it's a notebook, so changing card 
slots isn't possible.


Best regards
