First of all: it is 100% reproducible on the AS500. It triggers when
one (on a serial console) selects the terminal type and sysinstall starts.
I tried RC1 also on a NoName (AXPpci33) and that gives me:

These are the predefined terminal types available to
sysinstall when running stand-alone. Please choose the
closest match for your particular terminal.
1 ...................... Standard ANSI terminal.
2 ...................... VT100 or compatible terminal.
3 ...................... FreeBSD system console (color).
4 ...................... FreeBSD system console (monochrome).
5 ...................... xterm terminal emulator.

trap entry = 0x2 (memory management fault)

In other words: exactly the same trap.
Taking a long shot, considering that the DS10 boots OK:
Could it be that the generated binaries on RC1 only run on EV6 CPUs?
