intelfb: Do not ioremap entire graphics aperture
Probably this one. If vram is less than stolen size, intelfb
will only ioremap the framebuffer memory, excluding the
ringbuffer and the cursor memory.
Try booting with video=intelfb:accel:0,nohwcursor:0. If you get
a display, try this patch.
CC'ed Sylvain.
