/*****************************************************************
 Seems like a good place to track which letters are used for what:
   b - backdoor/registry
   i - interrupt debugging -> console, ethernet
   d - dma
   e - ethernet
   f - fpu (mipsy/embra/whatever)
   g - general -> memory allocation, checkpoints, gdb, etc. 
   o - solo-specific debugging (syscalls, etc.)
   t - tcl (including timing)
   v - visual
