Well, it turns out it can't be fixed. I've read the i810 man 
pages more carefully:

The  driver  makes use of the video BIOS to program video 
modes for the 830M and later.  This limits the video modes 
that can be used to  those provided  by the video BIOS, and 
to those that will fit into the amount of video memory that 
the video BIOS is aware of.

so modelines or anytthing else won't work.

There does appear to be some code that will with the video 
bios directly : 915 resolution @
