Radeon IGP 3D support is not only extremely experimental at the 
current state of upstream development, but it is not included in 
the XFree86 CVS tree destined for the 4.4.0 release, nor is it 
included in the DRI CVS yet to my knowledge.

I can state for certain that there will not be Radeon IGP 3D 
acceleration support in XFree86 4.3.0 in Fedora Core 1.

Hopefully, the issues present with the current experimental patch 
will be ironed out, and this support will make its way into 
DRI-CVS.  The XFree86 feature freeze for 4.4.0 is on Oct 15th, 
2003, so this is unlikely to be included in the 4.4.0 release 
either unless the XFree86 CVS commiters permit it into the tree 
without considering it a highly experimental feature.

Depending on if the 4.4.0 release hits it's targetted release 
date, Fedora Core 2 may contain XFree86 4.4.0.  During 
development of Fedora Core 2, I may consider applying the 3D 
support patches if:

1) Someone sends me Radeon IGP laptop or motherboard hardware 
with which to test/debug/etc.

or

2) Enough people test the support that it is considered at least 
as stable as any other Radeon support, and does not regress the 
driver at all.

I won't however just shove in highly experimental known-buggy 3D 
support for Radeon IGP, just because numerous IGP users out there 
are anxious to get 3D support.  It will be supported _only_ when 
it is considered stable and reliable upstream.  In particular by 
the developers working on it.

Hope this helps explain the IGP situation.
