What would be the best case scenario?
assumptions follow...
 -> IGP is just a northbridge with integrated radeon core.
Some limitations could be there:
1. low "local" memory, just for the framebuffer
1a) maybe you have to grab some more local memory for
higher resolutions (like i810?)
(look into XFree86-tree, when 2d-support for igp got added)
2. no local texture-memory -> agp-texturing only
3. no hw-tcl

unfortunately there is no agpgart support for the Radeon
IGP, so that's your first problem if #2. is true.
Or maybe you could try first if it would work with texturing
disabled in pci-mode.

greetings,
Andreas

Hi,

I was just wondering if someone has tried to do some reverse
engineering on the windows display drivers for the Radeon
IGP320/340. As far as I understand the IGP320/340 is based on the
Radeon 7000 (R100)? I'm not a display driver developer, but doesn't
this mean that apart from some differences in the interface to the
chipset a DRI driver for the IGP chipset would be largely the same
as the 7000 driver? I noticed that the Windows drivers are universal
(there's one driver dll for all R100 based cards), so maybe it would
be possible to disassemble it to find the code that detects the
chipset and sets up the hooks to address it and to find the
differences with the 7000 chips?

If this would be feasible, I'd be happy to spend some work on it.
Not that I pretend to be able to code a working 3D driver, but if it
turns out the existing 7000 driver could handle 3D on the IGP320/340
with minor modifications I might be able to get something to work.

I would really, REALLY like to have 3D support under linux on my
brand new laptop ;-) I already inquired ATI about linux support, but
I don't have the impression they are very willing to provide chipset
specs...
