There is a proposal submitted for the Qemu ARM PXA target
which looks to be the most capable ARM simulated target.
My thought would be to look at qemu's list of non-PC targets:

http://fabrice.bellard.free.fr/qemu/qemu-doc.html#SEC58

Then decide which look interesting to you and have
"high functionality" in qemu -- networking, graphics, etc.
Then lets see where RTEMS testing on simulators has
gaps.

+ some targets have no simulator support in RTEMS
that is useful for automated testing
  - Coldfire and SuperH come to mind
+ some targets have limited capability simulator
target with say no networking or graphics
  - MIPS, PowerPC

The Coldfire is an important target in the RTEMS world
and we do not have simulator support for it.  We have
a Board Support Package for the real hardware it claims
to simulate so this should be a relatively easy task of
getting the RTEMS image in a format qemu will accept.

I would be prone to combine this with a more involved
task like a BSP for the PowerPC or MIPS qemu configuration. 
The PowerPC is interesting because it is supposed to be
a PowerMAC and those are starting to show up cheap. :)

All the CPUs start to look the same after a while.  Some
are just weirder and more painful than others. :-D

Focus on running on a simulator first.  It is easier.
