Since it's not a realtime component, you can load it at any time.  You'd
have to hook up your hal nets at that time.

Alternatively you could change the gs2_vfd driver to handle
communication outages better, by going into some kind of dormant retry
state.


Buuuuut i have my doubts about both of those options.  IMO they are not
as good as simply wiring the VFD to come on when you apply power to the
machine, long before linuxcnc starts.  That would treat the VFD much
like the FPGA in the Mesa card - it's part of the control logic, and it
comes on with the rest of the control logic.
