This was fixed in both -CURRENT and -STABLE just after 3.3 was
released. *sigh*
Please apply the attached patch to /sys/i386/apm/apm.c and rebuild the
kernel, then all should be fine.
If you don't like to rebuild the kernel, you can edit your keymap file
so that it won't cause panic. You must be loading your keymap from
/usr/share/syscons/keymap. Find your keymap and locate the following
line.
057 ' ' ' ' nul ' ' ' ' ' ' susp ' ' O
~~~~
And change it to
057 ' ' ' ' nul ' ' ' ' ' ' ' ' ' ' O
~~~~ (a quoted space)
You must change the next line too.
104 slock saver slock saver susp nop susp nop O
~~~~ ~~~~
Change this to
104 slock saver slock saver nop nop nop nop O
