Items in bold are changes since last week.

The big thing in the past week is the work done on driverfs by 
Patrick Mochel, which started to appear in 2.5
If you are a driver maintainer, you may want to look at this :-)

As usual, let me know of any inaccuracies, and I'll be happy to 
correct them.
Enjoy!
