Well, it improves X support :) You had to put your monitor into 640x480
vga mode? I don't :) Are you missing the top two rows of the screen? What
happens if you try some other resolution, such as 832x624, or 1024x768? It
has to do with mmaping the framebuffer... at least on my 660av, the
framebuffer doesn't start on an even (4K) page boundary. Depending on the
video mode, it starts at 0x5010100, 0x5010f00, 0x5010600, and some other
places I don't remember. Anyways, if you're lucky (like in 640x480 mode), 
the offset from a page boundary is a multiple of rowbytes, and the screen 
is just shifted a few rows. If you're not lucky (like in 1024x768), X 
ends up drawing on the memory that's offscreen, and you get a blank screen.

Well the GENERIC-16 through 18 kernels have patches that aren't in the 
main source tree too :P
