screenblank doesn't unblank

[Matt Dainty <matt%bodgit-n-scarper.com@localhost>]

Is screenblank known to work okay? It seems to blank and power off the
LCD correctly on my Jornada 680, but I can't get it to unblank again
without stopping screenblank manually. I've tried running with no
additional flags, and also specifying the various /dev/wskbd* devices
with '-i', but the screen stays powered off.

Am I using the right keyboard device? Or is the wakeup code missing
somehow?

Cheers

Matt
