WMI vs Linux

Jamey,
google stumbled across this patch:
http://www.th.ph.bham.ac.uk/staff/schofield/linux/tc1100/linux-2.6.9-tc1100-wmi.patch
with your name on it.

I was wondering if you could tell me about it.
I was just about to write a little driver that binds to PNP0C14 and tells the user that they should not buy machines with WMI extensions and run Linux on them -- but maybe an exception to that rule already exists?

thanks,
-Len

ps. while you're at it, what is the WACF005 Wacom Digitizer device also in the patch -- I don't see that upstream either.

It would be helpful to export as much WMI information as possible - we can supply information to utilise it via HAL, which would at least provide support for doing things like poking the wireless and bluetooth hardware on the old HP tablets.

I agree that WMI functionality is generally a bad sign, but where we can drive it I think we probably should be.

It's handled by 8250_pnp.c now.

FYI, to whoever decides to bring this patch forward, "bluetooth" I believe should be changed to "backlight_control" or some such.

This patch exists in the Ubuntu kernels, too, and has been updated to work with recent kernels there.
