things like ACPI and peripherals is reserved so the OS can't use it,
so you get errors and ACPI failures and errors form LINUX saying
there is a BIOS bug that doesn't reserve the e840 region or
something to that effect.

* It obviously is screwing up ACPI because LINUX says the BIOS
isn't reporting power management capabilities for the Q6600 even
thouch ACPI, APM, SpeedStep, C1E, et.al. are all enabled in the BIOS.

etc etc.

How freaking hard is it to make a BIOS that works these days when you've
had what 20 years to practice getting it right over several dozens
of similar BIOS versions for similar chipsets?

I had some of these sort of usb issues with earlier P5K dlx bioses. I don't think it has much to do with the bios version at all actually.
