I have a dell XPS2 with a M770 processor.
I also had the CPU running high at idle after installing the 686 kernel.
I found this link and it works for me.
(I then had to CTLR-ALT_BACKSPACE or reboot to get it to use this modification.)

Add this to /etc/rc.local:

echo 1 > /sys/module/processor/parameters/max_cstate
Now I'd be the first to admit I'm no Linux Guru. My educated guess the problem is solely in SMP support in the 686 kernel being enabled for processors that have no need for it. (aka my Pentium M)

Anyways, I'm glad I can run the 686 kernel on my laptop with less cpu usage and cooler (The fans were kicking on all the time before this)
This is what you should do if you want to use a 686 kernel.
