I think it's really really lots of work. Basically you need to replace
everything which
looks like this:

#  file /opt/csw/bin/sparcv9/top
/opt/csw/bin/sparcv9/top:       ELF 64-bit MSB executable SPARCV9 Version 1

or like this

#  file /opt/jdk1.6.0_21/jre/lib/sparc/libjvm.so
/opt/jdk1.6.0_21/jre/lib/sparc/libjvm.so:       ELF 32-bit MSB dynamic
lib SPARC32PLUS Version 1, V8+ Required

with analogs looking like this:

#  file /opt/csw/bin/sparcv8/top
/opt/csw/bin/sparcv8/top:       ELF 32-bit MSB executable SPARC
Version 1, dynamically linked, stripped

Looks like only /etc can be kept more or less unchanged.

P.S. Btw, I'm looking for the OBP for U2. Do you happen to have .bin
or a serial console connected to U2?
