SVN rev 186026 on 2008-12-13 06:04:34Z by silby
Add the sysctl debug.acpi.batt.batt_sleep_ms.
On some laptops with smart batteries, enabling battery monitoring
software causes keystrokes from atkbd to be lost. This has also been
reported on Linux, and is apparently due to the keyboard and I2C line
for the battery being routed through the same chip. Whether that's
accurate or not, adding extra sleeps to the status checking code
causes the problem to go away.
I've been running this for nearly six months now on my laptop,
it works like a charm.
