There's a kernel patch posted to some linux-*@vger list a while ago that
does the SAK handling at a lower level than all the other keysyms. If
you can't find it in the standard mailing list archives, I might be able

having changed jobs and security policies since then.

Sigh...perhaps it's time for drivers/vga...
