>Environment:
System: NetBSD gnyf.t.dk 1.3E i386
>Description:
On a system of mine where apm_damn_fool_bios is necessary, apm0
randomly wedges the system completely because apm_damn_fool_bios
is only set in the 'suspend' case and not in the 'standby' case.
>How-To-Repeat:
Enable apm0 on system with lossy APM BIOS and wait a few minutes.
>Fix:
