SUMMARY: Can't get Sun to see new gateway hardware -- arp problem?

Many thanks to all who replied.  Craig Russell and Ed Rolison both informed 
me of the evil nscd daemon that in addition to caching nameserver lookups 
also caches a copy of your arp table.  Evil!  Evil!!

I ended up restarting nscd on the boxes, and then bringing the interface up 
and down to clear it all out.  Thanks to Tim Chipman for suggesting that 
with command stacking I wouldn't need to pull out my LOM cables.

Commands used:

# /etc/init.d/nscd stop
# /etc/init.d/nscd start
# ifconifg hme0 down; ifconfig hme0 up

Thanks again!  Original question below:
