[Cerowrt-devel] Pointers on build setup?

Regarding builds - can someone who is building cerowrt from source (including kernel) point me at the recipe for building it completely from scratch?
Besides running 3.3-2 on a 3800, I've begun my project to validate that Cerowrt can run on my ubnt RouterStation Pro box, which is preliminary to doing some experimentation on dense scalability that interests me. I verified that it runs the latest stable Backfire release of OpenWRT this weekend, and it does so quite well.
My own private home build server is (essentially) a cluster of two AMD8160 8-core 32 GB servers connected with 40 Gb/s Infiniband and a 6-way RAID5 storage array on one of them that gives quite nice read performance. I'm not worried about how long it takes to do a build...
Anyway - the recipe doesn't have to be perfected for me to use it - and I suspect it's similar to OpenWRT's build, so maybe pointing me to the best help for that and what the differences are would be great.
I promise I will write the "port" experience up and post it on the Wiki, in case others want to port cerowrt to other "OpenWRT platforms" of sufficient capabilities.

odd my laptop will do a full build with tool chain in about an
hour..... its only a core i3 with 6gb and an ssd
