Err, so?  The sysrq code is triggered by "ALT" (which on PPC can be any number
of things, depending on keyboard and other stuff) and the SYSRQ key.  It's
either 0x69 or 0x54, which is "F13" in either translated keycodes or ADB 
respectivly.

All of the USB keyboards, up until recently.

Well, where does that work?  My PReP works fine w/ ALT-printscrn-key
My old pmac is ALT-printscrn-key, and I don't have F13 on my other
keyboard.  So yes, I object because I'm not sure where your sugjestion
works.
