Subject: [PATCH] Framebuffer: Consolidated cleanup of pvr2fb.c for Sega Dreamcast

Tony,

Second time attempt at this and a much better job I think.

This patch consolidates your earlier patch, some cleanup of the
documentation and, crucially, some better handling of the pvr2
registers based on more up to date information.

Testing shows that it seems to work pretty well at 16bpp, 24bpp and
32bpp - including proper rendering of the boot logo at all levels
(previously this was a bit broken even at 16bpp) and giving white
against black text. Really detailed testing (eg with X11) requires
support for the maple bus - which isn't (currently - next project
assuming this is okay) available, but I have no reason to think this
is broken.

Incidentally, substituing DIRECTCOLOR for TRUECOLOR appears to break the driver.
