Many, many things have changed between 0.3.2 and 1.1.3; it would be
interesting to know why and where your kernel is hanging. You should
attach a debugger and actually try to *devbug* this insetad of
guessing (and blaming U-Boot).

No, definitely not. (Actually I can run the same tests on a
AT91RM9200DK, but this is not wired up for automatic testing in our
virtual lab, so I cannot run such tests remotely like I could do on
the cmc_pu2. But I know that it works exactly the same way.)
One of the things that did change is the mach-types.h file; if your
kernel uses some invalid ID this could explain such a hang. But this
is wild guessing - please debug the problem.
Best regards,
