Actually, we've set things up so that the distributed tarball should
build against a 1.2.0 server (and if you're building from upstream
source, you just pass the path to 1.3 server sources which it uses to
supply the missing bits in your 1.2.0 server). It means you don't get
RandR 1.2, but at least you would get the new native modesetting.
The new thing we need from the kernel is two 4-page physical allocations
(the 2 ARGB cursors) -- if you can't do this, you'll get a software
cursor on one head. I didn't bother to support more than one such
allocation in FreeBSD, because it used to only need one. The
alternative is that we could write some code in i830_memory.c that
decoded the GTT entries for stolen memory and used those for the
contiguous physical allocations. This would get us more efficient
memory use, as well.
For DRI, we'd like the 1.7 i916 DRM with the memory manager support, but
there are appropriate fallbacks if you don't have that yet.
