I wonder what would be the best option  here. The images are
necessary, so the last option - not complaining - can be misleading
for a user.

Concerning shipping them.
Pros:
- the images are obviously freely distributable (the link above).
- the corresponding source code was open-sourced by Sun under various
licenses (GPL for hypervisor, BSD for openboot).
Cons:
- there is no exact tag the the OpenSPARC source tree which would
correspond to the binaries.
- building them is tricky, because it requires Solaris 9 / SPARC.

What do you think would be a better option?
