In 2.4.21-pre7, I get the following:

The keyboard then goes away (at least under X, which makes switching to a VC impossible). Mouse still works, though. It seems like the system is very broken at that point, though. It's interesting to note, though, that SysRq still works.
Additionally, I've noticed that Ctrl+Alt+SysRq+S (dunno about other keys other than S) locks in the Magic SysRq stuff. That is, all keys pressed after that is interpreted as having been typed with Alt+SysRq. Is kind of a pain because, of course, you can't switch VCs or do anything but reboot. Plain Alt+SysRq+S works fine. (It might also be the fact that I've swapped CapsLock and the left Ctrl keys in my keymap, but everything works fine otherwise, so I dunno).
Thanks for any help.
