Subject: acpi + synaptics trackpad in 2.5

Whenever I run a ACPI battery monitor in X, my mouse goes completely
insane - goes around everywhere, and clicks randomly. the second i close
it, everything returns to normal.

Logs show no suspicious output when this happens.
I used wmbattery that Joey Hess edited to work with 2.5 ACPI, I have
posted it a website but I'm not sure whether it's GPL-compliant to post
it there and give the URL in this message without the source diff....
does anyone care at this point?

Regards
Josh

What machine?

When I turn on ACPI on HP omnibook xe3, keyboard/mouse freezes
randomly and I have to press power button to get machine back (power
*unfreezes* the machine).

Anyone seen something similar?

This is a Dell SmartStep 200N. I have no other working laptops using
ACPI so I can't know for sure how big a problem this is :)

Alright...
I know that some Dells (although I can't say whether yours is one) do their
ACPI by calling back into Dell SMM calls -- which takes the processor away
from linux for a significant amount of time; enough to cause clock
slippage, and loss of mouse data. And I'm guessing an ACPI battery monitor
polls at a fairly short interval, so, it could be related.
