Subject: Framebuffer support for HTC Dream
I cleaned up dead code, a lot of debugging infastructure and horrific
logo code. I had to remove earlysuspend support, because neccessary
headers are not in mainline. The driver still works :-).
I'd like to see it applied, working framebuffer is quite important for
debugging / getting other drivers into working state.

This adds support for framebuffer on HTC Dream smartphone (aka
T-Mobile G1, aka ADP1).
