You definitely want to turn off acpi. I didn't turn USB off since I use
it fro uploading pictures from my camera. Try moving the 1010LT card
around to see if you can get it on IRQ 9 or 10 by itself. I have almost
the same setup and I have:
CPU0
0: 15340768 XT-PIC timer
1: 6854 XT-PIC keyboard
2: 0 XT-PIC cascade
5: 0 XT-PIC usb-uhci, usb-uhci
8: 1 XT-PIC rtc
10: 33774 XT-PIC ICE1712
11: 1858859 XT-PIC eth0, nvidia
12: 351739 XT-PIC PS/2 Mouse
14: 627800 XT-PIC ide0
15: 1548341 XT-PIC ide1
It took me a few tries to get it to this point. Note that I don't have
anything on IRQ 9. I was unable to get it there but since I got IRQ 10
for my card it's OK.

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

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.
