That worked. The interrupts got redistributed like so: 6: 172 XT-PIC Intel 82801DB-ICH4, yenta 7: 3014 XT-PIC uhci_hcd, yenta, ndiswrapper 8: 4 XT-PIC rtc 9: 188 XT-PIC acpi 12: 1028 XT-PIC i8042

It piles the sound and cardbus onto IRQ 5, along with a USB that I'm actually using. For some reason it doesn't touch IRQ 6. Here are dmesg and /proc/interrupts from 2.6.1, 2.6.6 w/ acpi_irq_isa=12, and 2.6.6 w/ your patch:

That also worked and produced the same IRQ mapping as acpi_irq_isa=12.
Thanks! If you want any more logs, etc, let me know.
