Looks (almost) good to me but I'd prefer someone else to check it, to.

One thing though: We're using lzma per default now if we're using 
compression. This means each board needs at _least_ a stack size of 0x8000.

Those boards with STACK_SIZE being 0x2000 or 0x8000 are definitely 
broken (and if they boot, they do by accident)
