I've been experimenting with setting the framebuffer to 16 bits per
pixel instead of 18.
The driver accepts the value of 16 bpp when i do the ioctl, but the
display gets messed up and won't recover until reboot of the gumstix.
What happens is that the everything goes kind of green and you can see
the console cursor at four places on the screen, kind of interlaced.
Should I do something different from FBIOPUT_VSCREENINFO ?
This is with the Samsung LCD, console LCD and verdex board.
