That looks exactly right.

Hmmm.  Looks like something much earlier has failed to send a DHCP
request.  I wonder if the kernel command-line is being passed
differently by mboot.c32 and PXEGrub.

Can you attach a serial line or similar and compare the boot messages
printed in each case?  I'm not terribly familiar with opensolaris.
