I was seeing power usage like 750ma and the device was getting warm.  I 
tried rmmod libertas, rmmod hso and I didn't see any improvement.

All of the sysfs paths have changed, but  I did find the pressure input 
somewhere.  Did you get the updated udev rules for charging?

I enabled omap_pwm, but the gta04 didn't boot with that kernel.  I 
haven't connected the serial cable to see why.  The failure to boot may 
be unrelated to omap_pwm.  I will see if I can get it to load and make 
the backlight dimming work next week.
