I compiled 2.6.15.6 with gcc 3.4.3, too, just to make sure that this makes no difference. > I cannot test 1152x864 on my system because my monitor does not understand > that resolution. But if it worked previously it should work now ;-) Maybe you can test it with your monitor, too, see below. > Are there any problems on the framebuffer console?

No and yes: Everything works fine when using /sbin/modprobe cyblafb bpp=16 mode=1280x1024 ref=85 but I get the same problems if I do: /sbin/modprobe cyblafb && /usr/sbin/fbset -a 1280x1024-85 > Try a fbset -vxres 2048 -vyres 4096 after your first fbset.
