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 :).
