This probably won't actually solve the problem, but try it with just
apm=off (using ACPI), or just acpi=off (using APM). You might get lucky.
If you have neither off, the first to be initialized is the winner, and if
your kernel is modular, that depends on the order of loading drivers.
In kernel 2.4.x and previous, APM support was more mature than ACPI;
however, ACPI is mature in the 2.6.x kernels, and vendors put work into the
ACPI BIOS and not into APM. Some, e.g. Dell, have even dropped APM
entirely.
Might there be a BIOS update for your laptop?
