I have an i830M chipset which does the same thing, but don't have any
troubles with it. I have a line in my XF86Config that tells it I have
more memory, and I can happily run 1024x768 in 24/32 bits (it a laptop,
so there isn't much point to run any higher).

If you look below though, X claims to have told the card it has more
memory...

Well, that is a little bit more memory here...

Hello, this is even more video ram...

Ah, but this is less again, hmm this is strange.

Do you have a line in your XF86Config specifying the amount of Video Ram?
I have one and haven't had any trouble with it at all (other than the
acceleration being broken and causing all sorts of problems on virtual
console switching - I've been meaning to try a newer version).

Not a particularly helpful answer I suspect. Maybe try the XFree86 people,
I think it is more likely to be them than FreeBSD.
