Jamey was nice enough to hack up the devmem2 package to twiddle the asic
gpio port. He added a h5400-gpio program which can get and set the gpio
bits.

It's checked in to the cvs on handhelds.org as tools/devmem2

h5400-gpio -s 6 # turn on the backlight
h5400-gpio -c 6 # turn off backlight
h5400-gpio -s 7 # turn on lcd
h5400-gpio -c 7 # turn off lcd

Cheers,
Jason
