<strong>Hitting Ctl-Alt-Space may panic the kernel with the
apm driver which is disabled or is not functional because of
the lack of APM support in the motherboard.</strong>
Fix: To fix this, apply the following patch to
/sys/i386/apm/apm.c and rebuild the kernel.

If you don't like to rebuild the kernel, you can edit your
keymap file so that it won't cause panic. Find your keymap
file in /usr/share/syscons/keymap. Open it with an editor
program and locate the following line.
057 ' ' ' ' nul ' ' ' ' ' ' susp ' ' O
~~~~
Change it to
057 ' ' ' ' nul ' ' ' ' ' ' ' ' ' ' O
~~~ (a quoted space)
You must change the next line too.

Edit this to
