You don't have to flash every time you want to update pgserver!
OpenZaurus uses jffs2 as its root filesystem, so you can just copy
a new pgserver binary over the one that's installed.

Other methods include:
 - Keeping pgserver in a ramdisk
 - Mounting your desktop machine over NFS

I haven't looked at it yet, but I don't see how it could be anything but
the code in timer.c causing the problem. That code doesn't depend on
much else, so it shouldn't take much 'big picture' knowledge to find the
problem.

ssh in and kill it :)

Fn+C is only mapped to ctrl-c in Qt/E's console, not in the kernel. And
besides, ctrl-c won't kill pgserver since it needs to be able to send
that to clients like pterm.

The magic key for killing pgserver is ctrl-alt-/, but there's no way
(yet) to type that on a zaurus.

PicoGUI suspends the zaurus by issuing a command in /proc, but it
shouldn't have any effect on poweron.
