Here is a patch to fix CONFIG_APM=m in 2.5.69-bk11.  My patch to have APM
restore the systenter MSRs failed to handle the modular case, which fails
with unresolved symbols.

Since suspend.o is used from both APM (module or built-in) and ACPI sleep
(built-in), I made suspend.o built-in and dependent on CONFIG_PM.
