fw-5.6.1.1 -> PW-1, PW-3
fw-5.6.2.1 -> PW-2, KT-2, KV
Notes:
Older models unchanged (at least at this writing).
PW-1 is the only i.mx50 running fw-5.6.x, all others are i.mx6
5.6.2.1 is supporting both IR and Capacitive touch screens.
5.6.2.1 is also running with/without case buttons and adaptive front light.
Both firmware versions are supporting multiple screen resolutions.

I own three of the five models listed, and yes, I am pissed off (or pissed on by Amazon/Lab126) over this 5.6.x nonsense.
