Hi Alan, first: thanks a lot for your work to bring support for GMA500 to mainline kernel! My problem: with the current gma500_gfx driver of kernel 3.3.0-rc1 (pulled git yesterday 2012-01-27), the X-server is only shown in the top half of the screen after booting on my fit-pc2 [1]. The bottom half keeps the last output of the console. During booting the console is shown on the complete screen in the correct monitor resolution. I found a simple workaround: I only have to "stop lightdm" and do "start lightdm" afterwards. (same works with gdm) But maybe, you are interested in this bug and/or I can provide you some information to fix this. Personally, I have no idea to look for :-( Please let me know, if I could help examining this issue.
