joerg's kernel apparently only has "apm* at acpi*", not "apm0 at
mainbus0", so my test with userconf "disable acpi" is somewhat

- Pressing Fn-F1, the sleep button, still makes the machine sleep.
  (With ACPI it would print a message but not sleep).
- I do get messages about errors with the USB controllers when it wakes
  up. (same as below)
- /usr/bin/zzz says "zzz: cannot open connection to APM daemon: No such
  file or directory".

halt -p does not power off. (With acpi enabled it does: it mutters about
entering state 5 first).

So APM without support in the kernel partially works.

My installed system is from 14 december, just before the changes we're
really discussing, but if I apm-suspend with that, there are the same
complaints about usb and it doesn't work afterward (but I've seen
discussion about that already).

    uhci1: host system error
    uhci1: host controller halted
    uhci0: host system error
    uhci0: host controller halted

This is also a common message I see on various occasions:

    Devices without power management support: viaide0 vr0 lpt0 pckbc0 pcppi0 spkr0 fdc0 fd0

Maybe GENERIC should have "apm0 at mainbus0" so that the "real" APM
can be used with userconf and "disable acpi".
