All that's being done is the simplest possible bug fixing and 
refactoring to get stable drivers for a 3.0.0 release asap. xenidc is 
possibly a suitable alternative for future releases, after we have had 
time to look at it, integrate it with all the split drivers, and fix 
bug fallout. Given the size and complexity of the patch, I think it 
would be very high risk to commit to doing that in the next couple of 
weeks.
