Ok. I will be in my office in a few hours and will respond then.

Unfortunately not. The vanilla kernel comes with support for APM but not
ACPI (which my laptop uses). And that messes up the USB ports on my
laptop (ALi hardware issues). Its a long story.
I know I could probably compile from the source of 2.4.18, but I would
again need to compile the kernel module as above. Anyways.
Anyways, I will look into the documentation for compiling my own kernel
module. I hope that it will be as simple as creating a *.o file and
moving it to the modload tree.
