In 2.5.49: Can't compile w/ ACPI suspend states

[Eric Altendorf]

Hi, past few versions (at least 48 and 49 IIRC) won't compile w/ 
ACPI suspend states enabled.  Is this a known problem?

I run a crusoe machine and tried compiling for both crusoe and 
PII/Celeron procs, same problem.  I'm not using modules, FWIW.
More machine info & .config info available upon request...

Help!  I have a laptop and need to suspend (to ram or swsusp)!

Thanks, :-)
