There were no ppc hints to change, so I reconfigured it in the BIOS to
IRQ 7.  (I'm sure I had a reason to configure it on IRQ 5 at some point
long ago, but I don't remember why.)  This did not change the behavior
of the board.  And at this point, I would just as soon run with ACPI
disabled, since I don't know what I would gain by having it enabled.

It's another story on another machine I havem where ACPI is working
much better of 6.0-RELEASE than it had been under 5.4-RELEASE: a Compaq
R3120US.  I'm getting only three ACPI errors on this machine, whose
dmesg output is at:

http://www.m5p.com/~george/dmesg-6.0-R3120US.txt

Should I try to do anything about these lines:

acpi0: reservation of 62, 2 (4) failed
acpi0: reservation of 65, b (4) failed
acpi_tz0: _CRT value is absurd, ignored (200.0C)

or can I just ignore them?                              -- George
