They're talking about two different polling periods.

The _kernel_ has to poll the APM BIOS for status changes.  When it
sees a status change, it (in some cases) queues it to the apm device,
and in some cases just knows about it (I might be wrong on particulars
here, but you get the idea).

apmd listens on the device (which is the interface to the _kernel_, not
the BIOS) for power status changes and also does an occasional poll as well.

I believe that power status changes (such as line->AC transisions) are
sent immediately to apmd, where battery level changes are not (and that's
what apmd really polls for).

I think this sounds reasonable to me.  You have my permission to work
on it :-)

(If you don't have CVS access, I'll work with you to get any changes you
make into the tree).
