Henrik Forstén built a board with an Atmel ARM processor in 217-ball BGA package using OSH Park and OSH Stencil:
Making embedded Linux computer
I wanted to try designing a board with BGA chips in it to see how hard soldering them could be. So I decided to design a small ARM embedded system that can run Linux. ARM processor that I decided to use was AT91SAM9N12 in a 217 ball LFBGA package, just because it was the cheapest ARM processor with memory management unit which is required to run Linux.

this is pretty awesome… You’re the first person I saw making such a complex pcb project!
may I ask your help on directions for a projet of mine? i want to develop a barebone circuit to connect and controll a DLP 4.5” DMD chip directly from a raspberry pi or some other LINUX computer with GPIO’s…
Would you like to have a quick email chat about it so I can give you more details?
I’m not familiar with how to interface with DLP chips but you may want to checkout nanoDLP: http://www.nanodlp.com/
