- Cleanup up the driver (remove un-needed parameters, white-space, etc..), plus add a better display suspend function. - Changed the Copyright's to reflect the new 'jp.FreeBSD.org' email address.

Sanitize APM a bit. Convert various #ifdef to id_flags instead. You may want to add "flags 0x31" to apm0 if you have a lousy implementation. Read LINT. 1997-03-29 11:07:12 +00:00			`* Copyright (C) 1997 by Poul-Henning Kamp <phk@FreeBSD.org>`

Remove unused real-mode APM setup support. We've been using the vm86 mode initialiser for a while now, and it's looking happy. 1999-07-28 20:20:31 +00:00			`* $Id: apm_setup.s,v 1.13 1998/06/03 01:59:34 msmith Exp $`

This is the latest version of the APM stuff from HOSOKAWA, I have looked briefly over it, and see some serious architectural issues in this stuff. On the other hand, I doubt that we will have any solution to these issues before 2.1, so we might as well leave this in. Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much in the normal case.
