State-Changed-Why:
The i810 doesn't support linear framebuffers, even though the firmware says it 
does. From 
http://support.intel.com/support/graphics/intel810/sb/cs-009118.htm#POS13 :

Does the vesafb frame-buffer module work on the Intel® 810 and Intel® 815 
Chipset Families?
No. The vesafb module can only make use of linear VESA modes. The Intel® 810 
and Intel 815 chipset families use banked modes and therefore, cannot boot into 
a frame-buffer. It would be possible to add banked mode support to the vesafb 
driver, but as of yet there are no plans to do so. The vga 16 color 
frame-buffer available in recent Linux* kernels does function properly and can 
be used in place of the vesafb frame-buffer.
