Try disabling CONFIG_VIDEO_SELECT and/or comment out call to store_edid
in arch/i386/boot/video.S. Also which bootloader you use? From
quick glance at bootloaders, grub1 seems to set %sp to 0x9000, while
LILO to 0x0800. And I think that 2048 byte stack (plus something already
allocated by loader) might be too small for DDC call, as MGA BIOS first
creates EDID copy on stack...
