SubjectRe: laptop screen apm problems
Hi Steve,

Not having heard from you, I decided to tinker with apm.c to see if I
could solve the problem. In particular I compared it with the 2.4.18
apm.c (I had no problems with 2.4.18). The following seems to fix my
problem.

Changing line 1786 in apm.c (from the 2.4.19 kernel tree) from:
idle_period = simple_strtol(str + 12, NULL, 0);

to:
idle_period = simple_strtol(str + 15, NULL, 0);

solves the problem.
