I'm interested to see what the USB problem is with the standard rpi release or if it is gone.
Good point, I am very interested in this as well, I dont have FPGA's to test with but I was never able to reproduce the problem with either wheezy-raspbian or MinePeon, and I tried really hard.
IMO you are better to supply a script+downloads to produce your release from the base rpi release
MinePeon is meant to be a plug and play, lean and mean optimised mining build. Having to log in, download stuff, run scripts and configure stuff is something I am trying to avoid. I am trying to make it accessible to all, no mater what your linux skills are like.
