Hi!

Here are some implementation notes for FDXMS:

- It uses its own PM environment when doing XMS moves, so it's incompatible
  with EMMs (sorry, but people requested 64Mb support).
- If the move function detects that it can't switch to PM, an A20 error is
  returned.
- The move function uses MOVSD, so it's nearly as fast as possible.
- I didn't put much effort in optimizing the rest of the driver, as it's
  still beta.
- A20 switching is done using standard AT method (eg. programming keyboard)
- No command line switches are accepted (you can write them, but FDXMS doesn't
  care... ;) )
- XXMS isn't implemented yet.
- maybe I'll add virtual XMS support (swapping to disk)
- well, can't think of anything else...
