 We seem to agree on marking the XO-4 internal SD media (aka mmc3 in linux,
 address d4217000) as non-removable at runtime.

 The user would have to disassemble the system to get access to the
 motherboard, *and* remove the heatsink, all while the system is running.

 Marking it as non-removable brings in an added bonus: as this slot has no
 card detection mechanism, Linux will no longer have to poll continuously
 to see if a card has been inserted - freeing up some system resources.

 patch attached.
