Disabling power saver in RedHat

RedHat Linux 5
S3 Vinge DX

When leaving my box unatended for several minutes, the power saver functions kick in (inspite of the fact that I have disabled them at the BIOS level).

The S3 has a problem restarting the video services when this happens. If I am running in X I have to Kill X to recover video, if I am under shell I have to reboot the box.

Interestingly enough, this does not happen when using Slackware.

So the question is, how to disable (or configure) Power Management from RedHat Linux.

Recompile the kernel and take out APM support in "Character Devices".

See the Kernel-HOWTO.

there should be a DPMS option. No idea how to make this permanent.
