Thanks for all your input.  I think a reasonable summary is that 
although the documentation says it's not supported, if you're up to date 
with the firmware you might get away with it, but no-one in their right 
mind would risk it.  In theory you can bodge the buttons inside to 
offline the board and /usr/platform/SUNW,Sun-Fire-V890/lib/sf880drd 
should spot the fact and migrate everything off there to allow you to 
pull the board.  If you've made up with your favorite deity.

Anyway, scheduled downtime it is.

Thanks to Scott Lawson, Dean Ross-Smith, JayJay Florendo, Tim Bradshaw, 
and Joe Fletcher.  Your input is really appreciated.
