It worked to swap the keys once Solaris, Linux, OpenBSD and NetBSD (the
3 OSes I've run on my Sparcbook) have booted.  Both in the console and
after X11 was up.

I don't use your keycombo (^X^V) that I can think of, but I use
gnu-screen extensively, and I often use stuff like "^A^Q" or "^A^L" w/o
any ill effect.

Possible your keyboard has an issue?
