There are actually two drivers.

IEGD 9.1.1 is now publicly available and was updated to support newer 
Linux distributions, with Xserver <= 1.4. However, its VA API driver still 
has bugs (that are fixed for the next version). 
<http://www.intel.com/go/iegd>

"GMA500" (psb) is only available, for now, through ISV/OEMs. On a personal 
note, I would say to prefer that driver over IEGD. I think Canonical has 
now managed to fix their images for Dell (Mini 12), so this probably could 
be found there.

In other words, if your HW provider cares about the SW stack on it, he 
would/should already be shipping with decent drivers. Note, there is no 
fully Open Source drivers (3D, video acceleration parts) and I pretty 
doubt there would in the future since Poulsbo has Imagination Technologies 
IP in there. I can be proven wrong though, I that would be a good thing.
