I suggest that you test 2.6.22-rcN using one or both of these
boot options:

noisapnp
pnpacpi=off

Somewhere between 2.6.18 and 2.6.22-development, the ACPI config
symbol also starting enabling (selecting) PNP. That's one of many
differences....

I would also disable CONFIG_USB_USS720, at least for testing.
