I'll add a little more fuel to the fire here:
In the file /etc/osso-af-init/af-defines.sh there is code to define the INTERNAL_MMC_MOUNTPOINT to /media/mmc2. This is within an IF structure that tests if uname -m contains the string "armv6l".
This suggests a new processor that supports the ARMv6 architecture.

This Whitepaper on the ARMv6 architecture lists some interesting new features especially for multimedia.

Happy speculating
