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.
Cn Avg residency P-states (frequencies)
C0 (cpu running) (100.0%) 1.60 Ghz 0.0%
C1 0.0ms ( 0.0%) 800 Mhz 100.0%
C2 0.0ms ( 0.0%)
C3 0.0ms ( 0.0%)
Wakeups-from-idle per second : 79237.8 interval: 10.0s
Top causes for wakeups:

23.3% ( 51.1) mpd : schedule_timeout (process_timeout)
20.3% ( 44.5) <interrupt> : 0000:02:09.0
1.8% ( 4.0) thunderbird-bin : futex_wait (hrtimer_wakeup)

0.7% ( 1.5) openvpn : sk_reset_timer (tcp_delack_timer)
0.5% ( 1.1) xfce4-panel : schedule_timeout (process_timeout)

0.5% ( 1.0) wpa_supplicant : rt2x00lib_config
(delayed_work_timer_fn)
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.
