You can build an image with dsp support by following the notes at:

http://ettus-apps.sourcerepo.com/redmine/ettus/projects/usrpe1xx/wiki/Install_OpenEmbedded

I'll post a copy of the image next week.

To run the demos, you'll need to modify the kernel boot args to create a 
memory hole. This is (barely) documented on the interwebs. Next time I 
update u-boot, I'll include an extra variable to make it easier to 
create the memory hole.
