Intel distributes the code as a tarball. They do not provide  
individual patches.

To the best of my knowledge, Intel or a contractor of Intel does all  
current work on the driver. I am told that Tungsten Graphics has not  
been involved for several months.

Unfortunately getting access to a git branch by hosted Intel is not  
likely to happen - especially in the timeframe required by the OEM team.

Luckily this particular driver affects only a small number of OEM team  
projects. I have been in contact with all of the relevant project  
leads, they are all looking forward to having this update included in  
the hardy/netbook-lpia tree (and future Poulsbo updates, as they  
become available).

The Poulsbo graphics driver stack does not fit in well with the rest  
of the kernel/graphics stack in Hardy (or Intrepid/Jaunty, for that  
matter). Nobody likes this situation, but we have to make the best of  
it. I am in no position to dictate how the kernel is maintained, but I  
will throw out the idea that perhaps this particular driver be treated  
as a binary blob - updates are all or nothing, and we accept that the  
patch quality may not be up to the standards of the rest of the kernel.
