You can find the main svn repository at...

svn://bits.cs.uic.edu/strangers

The openwrt directory under strangers contains both the source to build openwrt and binaries for flashing a ubiquiti (atheros) device. Normally you don't keep binaries under source control, but in this case it makes sense since openwrt can take an hour or more to build.
