Well, I just tried suse 9.0 with a vendor provided smp kernel 2.6, and 
they don't appear to have acpi enabled.  Would you like me to compile a 
custom kernel?

I was really enjoying the use of acpi as I was able to power down the 
machine by simply hitting the power button.  "Imagine that!"  I did have 
to fix several errors in the DSDT, but acpi was working okay, timer and 
all, or so it seemed.

Thanks guys,
Pete...
