PROBLEM: resume from APM screen blanking locks keyboard

[1.] One line summary of the problem:    

On an Evo N410c, BIOS version F.0E A (26 Feb 03), with the AC adapter
unplugged (for some reason, with the AC adapter plugged, the screen
doesn't blank), the screen blanks after a few minutes of inactivity.

When hitting a key, the screen resumes, but the keyboard locks up and
the machine has to be turned off. The processes keep running, but
there is no way to interact with them.

[2.] Full description of the problem/report:

This behavior has been happening with and without
CONFIG_APM_DISPLAY_BLANK, with and without CONFIG_APM_ALLOW_INTS.

I tried to use setterm to disable screen blanking too, but it doesn't
work either.

[3.] Keywords (i.e., modules, networking, kernel):

APM, screen blanking, keyboard lockup

I put the rest of the bug report as documented in REPORTING-BUGS as a
compressed attachment. I am not sure how to debug the problem, but am
very willing to try things out and send more information.

Regards,

Hugo
