Pre 2.2.7-4 SysRq problem/bug?

When I use ALT-SYSRQ-M in a regular user (not root) session in an rxvt
session under X, it
misinterprets the command and seems to do an Alt-sysrq-s Alt-sysrq-I and
Alt sysrq 6.

When I switch to a console with ALT-F1 (with X still running)
and do any alt-sysrq it does the command properly but it also puts the
keyboard in a funky mode that has it act like the ALT-sysrq is still held
down.

(in the log below thats the SysRq: unRaw.... lines. I was just hitting
return to get a shell prompt)

The keyboard seems to clear that funky mode when I change the console
logging with
ALT-SYSRQ-8. UnRaw does not seem to work.

Machine is Cyrix M2/167Mhz, 64M, 512K cache, ALI chipset. Distro is RH5.2
with
updates for 2.2 from RH. XFree is version 3.3.3-1.1 (from RH updates
distro) XServer is SVGA on a Virge card

This is 100% repeatable.
