Ah, not seen that, mine goes thus:
- Config from 'X -configure' gives a very weird corrupt display which
is allegedly 640x480. DDC failure is likely cause of resolution
(II) VESA(0): VESA VBE DDC supported
(II) VESA(0): VESA VBE DDC Level 2
(II) VESA(0): VESA VBE DDC transfer in appr. 1 sec.
(II) VESA(0): VESA VBE DDC read failed
- Wedge some Horiz/Vert values into the Monitor section to pretend
that my LFP can do more than that, I get a blank screen but
apparently it's correctly running 1024x768.
- Go back to original config, but with "vesa" driver. Get 640x480
but at least it works.
- Wedge values back in and successfully get up to 1024x768, but well,
it's the vesa driver...
So I can't actually test whether the AGP driver helps or not, only
that doing some basic stuff to /dev/agpgard works.
Someone with more driver-fu than me being able to fix the i810 driver
would probably be more useful than just the AGP bit. Worryingly a
semi-recent Ubuntu live CD doesn't work either so maybe this
particular model simply isn't supported.
