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.
