Remove APM BIOS support
APM BIOS was relevant only to early laptops (approximately P166 or P200 and slower). These have not been relevant for a long time, and this code has been untested for a long time (as far as I can tell). The APM compat code in ACPI and the apm(8) command is not being retired. Both of these items are still in use (apm(8) is more scriptable than the replacement acpiconf, for the most part). This has been commented out of i386 GENERIC since 2002. This code is not relevant to any other port. Discussed on: arch@
