I can certainly give that a try - but maybe I really have already.  My
frontend system uses forcedeth for eth0, which is blacklisted by
hibernate-script.  So I see eth0 dropping and coming back as part of
suspend.  I suspect the trick is having Myth be on the right screen when
this happens.  When I was suspending with Myth active, sometimes it came
back OK, sometimes it came back with the "connection lost" dialog, and
sometimes it would just crash.

Unfortunately, when I try to "jumpmainmenu" on this system, it jumps to
the main menu, then goes to LiveTV - every time - from the remote or
telnet/nc.
