I did not have time to read all your code, will try later.
To get to the frame buffer on sandybridge, you just read one of the BARs, I think i't BAR 4. That won't work on the x60?
I just found out that the bar2 where the framebuffer is on the x60 isn't mapped correctly:
common.c maps the framebuffer and then I do that with the virtual address: (gdb) set {int}0xa7d38000 = 0xff (gdb) p/x {int}0xa7d38000 $1 = 0x0
0xa7d38000 points or at the beginning of the bar, or at address of the framebuffer(I took it from the kernel with kgdb).
I am told by phcoder on IRC that I've to activate the access to VRAM...
