The National Conference of State Legislators has put up a "Countdown to REAL ID" page. There a lot of great resources there, as well as a database inventorying various state legislation concerning driver's licenses and identification cards.

Countdown to REAL ID:

As the May 11, 2008 implementation deadline of the Real ID Act approaches, states are facing an uncertain future. The U.S. Department of Homeland Security (DHS) has failed to release regulations and Congress has appropriated only $40 million to assist states with the implementation. Without adequate assistance from the federal government and regulations to guide state efforts to implement the Real ID Act, state driver’s license security is at a stand still. 

As I write this, the countdown says:
444 days, 10 hours, 44 minutes, 01 seconds

Wouldn't be bad to see some regulations come out of DHS at some point, eh?
