Hi,

I've just make patches for the recent apm module changes.

http://people.freebsd.org/~iwasaki/apm/apm_module-20011025.diff

The problems I'm tring to solve are;
 - Apm loadable module cannot inform other kernel components whether
   apm will be enabled (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
   SI_SUB_KLD stuff should be invoked earlier than SI_SUB_CPU.
 - APM and ACPI cannot co-exist together at the same time according to
   ACPI spec.  They should be enabled exclusively by some sort of
   arbitration mechanism.
 - Now that `#ifdef DEV_APM' related code is almost obsolete.  Also
   public apm(4) functions, such as apm_suspend(), cannot be called
   directly, should be called via abstracted interface.

Note that the patches contain exchanging priority of SI_SUB_CPU and
SI_SUB_KLD.  I already checked dependency of all MOD_LOAD code on
cpu_startup() related code (e.g. DELAY) roughly, but I'm not sure if
there is no problem.  I think that module load event code and kernel
linker should not depend on SI_SUB_CPU...

Any comments are welcome.  I'll commit this early in Nov.

Thanks
