Software Errata:
- Any code accessing the ethernet controller's registers must be in an even page of memory!
- The SD Card controller's "raw access" mode only works so long as you don't initialize the controller. Once you've invoked the init function, raw access will fail until the next reset.
- A special "song-and-dance" routine is needed to switch from 800x600 back down to 640x480. See the various kernel sources for details.
