The internal device controller often can do the mapping transparent to the user, but this device looks like it will need a bit of manual help with the chore.

The mmc devices in the newer kindles do all this mapping in software (kernel mode device drivers *and* in the u-boot code). They also do all the error detection and error correction in software. You can examine it in the GPL source code.
As I recall, on the touch, there is 64MB of spare blocks scattered across the device, and when these all get used up you will start seeing errors "leak through"...
