Problem w/ ACPI in -CURRENT

There may be a problem with the ACPI drivers in -CURRENT. I cvsup'ed to
-CURRENT earlier today (9/23/03), rebuilt the world and kernel, and installed
everything without incident. When I rebooted my laptop after installing
the world, the kernel started hanging part way through the boot process.
I played around with it some, and found some things out about what was
going on.

When booting FreeBSD with verbose logging on, these are the last
messages displayed.

acpi_acad0: acline inititialization start
acpi_acad0: On Line
acpi_acad0: acline inititialization done, tried 1 times
acpi_cmbat0: battery initialization start
^^^ hangs after that

When booting FreeBSD normally or in single-user mode, these are the last messages displayed:
Timecounter "TSC" frequency 498470127 Hz quality 800
Timecounters tick every 10.000 msec
^^^ hangs after that

When booting FreeBSD with ACPI turned off or in "Safe Mode", the computer boots normally.

Rebooting with either of those options, however, leads the kernel to
complain about some processes not dying. I'm not sure if that's relevant
to this problem, however.

When booting with the old kernel from 5.1-RELEASE, it booted OK, but
complained some (as one might expect).

Right now, since the laptop boots with ACPI turned off and the verbose
logging seems to die when it's doing something with the battery, it
looks to me like the problem is there. Right now, I'm building a new
kernel with debugging support turned on, so hopefully by tonight I might
know more. Has any one else come across this problem, or is it more
likely something on my end?
