With kernel 2.6.20-rc4-mm1 and all hotfixes, i810fb fails to load on my
Dell Optiplex GX110. Here's an excerpt of the diff between the boot logs
of 2.6.20-rc5 (working) and 2.6.20-rc4-mm1 (non-working):

Hi Thomas,

This also fixes X starting on old i810/5 hardware, I had noticed it
broken but hadn't had time to investigate it, this patch fixes it...

The oldest hardware I have is an i915 which hampers me a bit.
