I've seen kludges around that make this work; you might poke about a bit 
and report back if you find something that does the trick for you.

Nope.  Turns out it's "hard" because the i810 doesn't actually contain all 
of the hardware needed to drive the display -- half of it is in an 
external chip, and there are *many* possible chips for that job, none of 
which are made by Intel and none of which have opened up their 

So, we have to rely on the BIOS to set up those external chips.
