You can query it by typing 'apm'. I got the values by checking the status
in winCE and then quickly boot netbsd and query the status.

No, "suspending" doesn't really work, only the screen is actually
turned off in "suspend mode".

And there's no config file needed at all.

But please note that the pcmcia bus is only 16-bits wide.
32-bits (cardbus) cards will not work.

Yes, sometimes it just doesn't work... I noticed that increasing timeout
to 500000 in j720ssp.c:j720ssp_readwrite solves this, but I've no clue why
a longer timeout is needed for the power button.

And in addition, the modem and irda also don't work.
