The slacker that supports GNURadio in OE hasn't added a recipe for 
3.2.2. Wait, that's me! Still for this discussion 3.2.1 is fine.

Most of my time is spent on the git recipe in OE. If you comment out the 
DEFAULT_PREFERENCE line in that recipe, you will get or more recent 
build. I haven't built it on an ARM9 recently, there may be some issues 
with atomic operation support in boost.

My understanding is the same as Tim's, you will need some form of GigE 
interface. Unfortunately, the DM6446 does not support full HS USB host, 
but it still might be possible to use a USRP1 with it. A quick read of 
the docs suggests this might work.
