[ltp] Hot Sleep

[James McKenzie]

Crispin and others:

ACPI is NOT ready for production, it is still in testing.  I suggest 
using APM to suspend to ram or disk until it is ready and STABLE.   I do 
not use ACPI with my A22p because of problems suspending to disk with it 
to the same drive files for Windows98.
