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...
Denis.
