Wonderful and encouraging news!  In particular, do you have Suspend to
Ram working on on lid-close, and Suspend to Disk (hibernate) working
both on demand and automatically when the battery is about to run out?

I haven't the patches yet, so I'll apply those and see what happens.

Do you know if the acpi_sleep option is (as the name implies) ACPI
specific, or does it do something for APM as well?  Also, I can't find
mention of it in my kernel---do you know where it is actually handled?
Is it part of the base kernel or of one of the patches?

That would be great.  Could you start by sending me just your .config?

OK.  I like the apparent simplicity of the APM approach (ie, let the
BIOS handle it) but if ACPI is working for your that's reason to switch!

Thanks!
