to be precise, this is not 950 graphics:
0.2.0: vid 03.00.00 8086/2772 10 0:fe980000 524288 1:0000cc01 16 2:e0000008 268435456 3:fe940000 262144
Intel Corporation 82945G/GZ Integrated Graphics Device
the intel atom machine i've been working with keeps
doing things i'm very happy with! i got a chance to check
out the vesa graphics and they seem to be very well.
1600x1200x16 works just fine. the vga timings are perfect.
and even pictures don't look too bad. since i'm using pat
rather than mtrr, adding the newly-added vesa->flush()
fixed the slight niggle i was having with a jumpy pointer.
now if i could just get someone to build the same thing with
intel 82574 nics....

Hmm, perhaps I am confused (it wouldn't be the first time). My
understanding was that the 82945G implements the GMA950 chipset. Come
to think of it, I'm not entirely sure why I thought that?

I really wish I could do 1680x1024xwhatever.

That reminds me, I've been meaning to ask you a question. I'll send
it off-list.
