Yes, whatever was flashed on it when Samsung last had the board.  The
bootloader does explicitly say it's looking for the SMSC chip when
setting it up.

Yes.

Factory default - I can't immediately visualise which switches you're
talking about and I'm out of the office until next Monday so I can't
check with the boards how they're set up.  I don't recall any relevant
switches.

I'd expect so.  

I'm not sure what you mean by the "machine definition file" here?  The
large number of non-probable and incompatible changes on the Samsung
boards mean that it's generally best to leave them at factory default
settings unless you have a particular need to change things since the
kernel tends to be configured for the default setup.
