While this may be irritating because it's not really answering your
question... They're not the only possible evaluation boards;
Algorithmics' P-4032 has been around longer (so may have less
undiscovered bugs) and has advantages:
o A decent OpenBSD port available now (which includes a working super
VGA X11 graphics system).
o a two-year-old Linux port which was kind of done
o A port in progress with someone in the US (name available
privately).
o Help and encouragement available from Algorithmics, who are the board
designers.
o A free board to anyone who is serious about getting a good Linux up
and running.
o P-4032 supports not only Vr43x0, but the QED RM5230 and IDT 64x74
CPUs too.
o A familial connection with the big-brother P-5064 board, which
supports CPUs right up to the RM7000.
