But that still does not explain why RedHat AS3 works on the same machine
with the same BIOS settings without specifying any acpi related
parameters. As far as I can tell, AS3 is using an older version of the
ACPI code. It reports "ACPI: Subsystem revision 20030619" when
booting. So barring some hack RedHat has in there, clearly something
has changed along the way to break things on this machine...

Thanks,
