OK. My APIC is a SiS961.
I can't send data from 2.6.6-rc3-bk8, but from 2.6.6-rc3-bk6,
/proc/acpi gives:
(/proc/acpi/processor/CPU0)
processor id: 0
acpi id: 0
bus mastering control: yes
power management: no
throttling control: no
limit interface: no

cat /proc/acpi/sleep shows:

cat /proc/ide/sis shows:

... I don't know if any of this is helpful. The IRQ and IO address
assignments (sent with my first email) are from 2.6.6-rc3-bk6.

Thanks,
Bob
