The CAN stuff is also available in the 'SocketCAN' SVN for older 2.6 
Kernels and i backported the latest code to Kernel 2.4 two weeks ago as 
some people still use it. As a change in bcm.h is user visable i just 
wanted to freeze the latest version of the header files into a 
consistent CAN version for Mainline, older 2.6 and 2.4 Kernels. That was 
the reason for creating version 20071227 *before* it hits a released Kernel.

Thanks
Oliver
