Isn't going to happen.
At least 32 bits, linear model, not paged.
Not only that, Linux requires much more memory that is internally available on any MCU.
The smallest freescale mcu with Linux is the V2 series. For processors without an MMU uClinux is used.
I recommend uCos.- there is a port for Dragon12 that works great. It can be downloaded from thier site.
