And, if you have another OS on the machine, do you have any hardware
monitoring working there?

Using 2.4.21 or even 2.4.22-preX with a recent ACPI patch would probably
make it behave as 2.6.0-testX does.

00:02.1 being the SMBus device, I suspect all these is related.
Obviously, your BIOS manufacturer did not allocate an IRQ for the device
if ACPI isn't used, and did not allocate an adequate I/O space, if I
followed your discussion with Mark M. Hoffman correctly. I suspect they
just don't want you to use the device yet. As you say in your other
mail, a newer BIOS may help someday.
Maybe you should contact Packard-Bell and ask them about it?
