powerpc power management

[John Rigby]

I need to implement suspend to ram (sleep mode) on an embedded powerpc
processor.  I have googled generally and searched the lkml, this list
and the linux power management mailing list.  It seems after all this
searching that the only existing code is for the powermac in
drivers/macintosh/(variousfiles) and
arch/powerpc/platforms/powermac/(variousfiles).  Is this true or am I
missing something?

Thanks
John
