@ Kelly :
I guess you are right. I can almost say for sure that it is due to the pcmcia
modules. There was no bad state for the 27 hrs after which I had rebooted (to
play my favorite game in windows :p). And I tested again with pcmcia modules
loaded and there were high wakeups within a few hours (3-4 hrs). And in that
case, laptop_mode is not the culprit ;). Anyway, I'll try to test for a few
days of uptime in a stretch if its indeed solved (as of now, nothing in last
7hrs).
At the moment, the only reason I can see is that the pcmcia, my ipw3945
wireless card (and probably a usb port also) share the same irq 18.
@ Jan :
So it seems that your problem is slightly different from ours ;). But looking
from above, I guess you may try disabling some driver modules for devices you
don't use, to avoid irq sharing as far as possible and see if it helps.

I have the same weird problem with my AMD-based Medion MD96400 Laptop.
Some time after booting it goes up to ~80000 wakeup/s and stays there. I
can shut down X and remove all modules, no change at all. When I
reactivate the notebook from S3, the wakeups are gone.
I never have pcmcia/yenta_socket loaded so I guess that's not working
for me.

Another thing I discovered is, that my Laptop switches only between C0
and C2. C1/C3 are never used at all. HPET doesn't seem to work.
