Now that's a reason :-) 

Well, i think i've muddled things up. I found the document i was
looking for, and it's apart of the agpgart linux module released @
http://intellinuxgraphics.org/:

agp.h:
#define I810_GMADDR             0x10
#define I810_MMADDR             0x14
#define I810_PTE_BASE           0x10000

intel-agp.c:
#define I915_GMADDR     0x18
#define I915_MMADDR     0x10
#define I915_PTEADDR    0x1C

So unless the GMADDR and the GTT Base address are the same thing, i've
muddled up the patch. Intel has changed things around, no dobt,
however.

AFAIK FreeBSD agp driver doesn't support 945 chipset:
with a bit of hacking (aka add the appropiate ids in the appropiate
files) it will attach, but it won't work.

That was the situation when i last tried to make my 945g work
a couple of months ago, and so far i don't remember any progress
on this front, but you can prove me wrong here... :)


It works for me, provided i use a limit with the VideoRam option in X.
I havn't had the time to play around with it, and if need be i'll use
an OS that fully supports my i945GM (Even though i do love FreeBSD :).
