and here are the interrupts from the (seemingly working) EeePC's Xandros 
2.6.21.4 install:

            CPU0
   0:       6486    XT-PIC-XT        timer
   1:        107    XT-PIC-XT        i8042
   2:          0    XT-PIC-XT        cascade
   3:          0    XT-PIC-XT        uhci_hcd:usb2
   5:        735    XT-PIC-XT        uhci_hcd:usb1, ehci_hcd:usb5
   9:        219    XT-PIC-XT        acpi
  10:       8171    XT-PIC-XT        uhci_hcd:usb3, pciehp, wifi0
  11:        107    XT-PIC-XT        HDA Intel, i915@pci:0000:00:02.0, 
uhci_hcd:usb4, pciehp
  12:        236    XT-PIC-XT        i8042
  14:          0    XT-PIC-XT        libata
  15:       3475    XT-PIC-XT        libata
NMI:          0
ERR:          0

and here is the kernel cmdline that the Xandros install uses:
quiet rw vga=785 irqpoll root=/dev/sda1

I've got a feeling I know what direction this is going in...
