Please try to deactivate everything related to framebuffer and specific
video hardware in your kernel config. See if it helps, then activate one
option at a time until it breaks again.

Specifically:
CONFIG_FB=y
CONFIG_FB_BOOT_VESA_SUPPORT=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_TILEBLITTING=y
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y

The only thing you really need for the start is CONFIG_VGA_CONSOLE.

Hope this helps,
Florian Philipp

P.S.: Please don't top-post in the future. Use an email client that
allows you to write your response below the text you quote. That makes
large threads easier to read.
