Interesting console problem

I had an interesting console problem with 2.1.126 just recently.
tty6 was allocated, but blank (no getty process running on it) however
when I switched to it,

1.) The scroll lock keyboard light was on and even when I hit scroll lock,
it stayed on. Switching to another VT, scroll lock worked fine, but when
I switched back to tty6 the scroll lock was still locked on.

2.) After being in tty6 fooling with the scroll lock, num lock, and caps
lock keys (none of which did anything, scroll lock was on but the other two
were stuck off), I switched to another VT (tty4) and was about to type
"deallocvt", and when I hit the "d" key, it typed out about 80 'd's at
one keystroke. CTRL-U'ing that, I typed deallocvt and it worked successfully.

Actually, now that I did a little test with tty6, I see that the three console
keys (scroll/caps/num lock) are stuck off when I create the terminal (open
/dev/tty6 but promptly close it), but when a process is writing to the terminal
the console keys are free to be switched on/off.

It's the 80 'd's that were typed when I switched to another VT earlier that
has me boggled.
(That didn't happen the second time around when I did the open/close /dev/tty6
test)

Hardware specs:
HP Vectra 486 DX/33 (S3 localbus video hardware)
Running it in 132x34 video mode (132x25 initially, with a
resizecons -lines 34 in my /etc/rc.d/rc.S file)

Hope this helps with the bug tracking.
