The latest 2.5 status update is available for your enjoyment at 
http://kernelnewbies.org/status/

All the desktop users that care about interactive feel may want to give a 
whirl to 2.5.4 that adds an option (disabled by default) to preempt the 
kernel, courtesy of Robert Love based on original work by MontaVista.

I have not heard from a few projects in the list below in quite a while, 
so please let me know if you can spot anything out of date or incorrect.

Cheers!
