Subject: Re: [PATCH] HP mobile data protection system driver

Hi.

I finally got 2.6.19-rc2 to work on my laptop and it apparently fixed a bug 
related
to MDPS's IRQ handling, so I was able to register the IRQ handler.
I created a newer version of my driver that can now act on interrupts
from the device instead of doing polling on the position that the 
accelerometer
reports.
I wrote an interface that is still compatible with hdapsd + made a misc
device that acts similar to /dev/rtc - I also wrote a user space daemon 
(it's very
easy now) that can print something like "your laptop is falling: press any 
key to catch it"
whenever I drop it 10-15 cm and catch it.

Attached is the patch that applies to 2.6.18 and 2.6.19-rc{2,3}.
I didn't inline the patch, since hotmail screws it up.

Any comments are welcome.

Also, should I send it perhaps to the hwmon maintainer as well?
