I don't know which R5000 you are using but QED designed the original
R5000 and sells a compatible RM5200 series. We've had customers move to
Linux. I've recommended using the Cobalt Cube as a starting point since
its already a commercial product using the RM523x CPU and Linux. You
can find more info at www.cobaltnetworks.com. The distrubution can be
obtained at ftp.cobaltnetworks.com.
I don't know how close to current Cobalt is but the low level CPU code
may be of use.
