- It is ugly that a daemon needs DISPLAY to be set but we can survive
- I don't remember if the "make" suspend synchronous changes of sandman where
ever merged upstream. You need to make sure that system("apm -s") only returns
until after the suspend. There is little guarantee and with Opie we once had a
problem like this with the apm emulation (but that was in 2000). Just keep it
- Alternatively you can enable kdrive's apm bios handling again that could
solve this issue nicely. You might need matt's help to debug any issues coming
from apm_bios.c kernel features (we all know linux is bug free).
