No worry there.

I mention Microsoft not to advocate that Linux be Windows,
but to point out that this (hardware/firmware) ship sank 5 years
ago and Linux is still on the boat.  MS was able to delete 
APM support in 2006 from their source tree, yet we still carry it.

They can still run old Linux on an old APM-only laptop --
just like they can still run Windows 3.1 or Windows XP if they want to.

What we'd be taking away is their ability to run the latest
Linux kernel on that laptop.

The issue at hand is people (like me) who have to maintain
the latest Linux source code.  In sort, I don't want to
write, debug, and test a cpuidle driver for an apm-only laptop
when I could be spending effort on code that people will
actually run.

thanks,
