On my newest machine, an ASUS P3B-F mb with a PIII, running
kudzu during boot has the negative effect of disabling APM suspend.

To be precise: the machine does suspend, but only for a fraction
of a second (the monitor is turned off and the suspended led is blinking).
However, the machine then immediately wakes up _as_if_ I had
touched the mouse or keyboard.

I tried different kernel versions (suspecting the APM driver)
and BIOS versions, but nothing helped. Eventually I traced the problem
to kudzu. Suspend works if I tell init to not run kudzu at boot.

I'm pretty sure this wasn't a problem prior to RH 6.2 -- I recall
trying suspend mode last fall when the machine was new, and then
it did work.
