Proper creation of /dev/apm_bios

Background for debian-devel:

On certain (many?) machines, the new X packages will cause the console to
completely hang after waking back up from being put to sleep.  This can be
fixed by having /dev/apm_bios and appropriate kernel support.  The
powermgmt-base package does this, but on PowerPC, it is not installed by
default, leaving PowerPC laptops in a situation where they are easily hung
by default.

That would be fine too -- even ideal.  Or a dep on powermgmt-base by
domething.  Powermgmt-base appears to be better because it also handles
devfs, though I'm not familiar enough with devfs to know exactly what that

To date, xserver-xfree86 is the only package I have observed that fails
catastrophically without /dev/apm_bios.  Most others work with entries in
/proc.  However I'm certainly fine with having it done on a more global

Could be; like I said, knowing the info in this bug's history, I agree that
it may not be a bug in X.  I just disagree with your decision to close it,
and feel that it is still a bug that perhaps needs to be reassigned.
