This is strange.  I copy-n-paste the code that checks AC line status
from apm, so ichctrl should do if apm works.

Estctrl uses hw.acpi.acline to check AC line status.  But I notice
ichist doesn't rely on neither ACPI nor APM, so I decide to check AC
line through /dev/apm since it's available in both configurations.

Are you using vmware?  I think rtc module is needed to run vmware.
It barks if HZ is not high enough.

Estctrl checks kern.cp_time twice a second.  Since ichctrl is derived
from estctrl, it does so too.  I'm not sure if HZ has anything to do
with it here.  In my kernel config, I set HZ to 1500.  This is because
I used vmware before, and rtc barked all the time. :p

ichctrl 0.1 is released.  It's at
http://svn.ntcu.net/~plasma/ichctrl-0.1.tar.gz.  The length is 2532,
and md5 8ba185c774af55235277d2cf8a1cbaba.  Maybe you wanna give it
try?

Sorry, your problem really beats me.  I have no clue what's going on.

Maybe I should write a version which uses hw.acpi.acline to test AC
line status for you.
