Just a follow up for the archive:
I guess the way I set up the lcd823 driver for my kernel made it
so
that a 10 minute console blanking feature was enforced. Since I also
have a custom keyboard driver, it never unblanked the screen. To solve
the problem for now, I just set drivers/char/console.c blankinterval = 0
to disable the problem/feature.
Thanks,
Jim
