Well yes and no. Last year I worked on a CERN/TRIUMF project using
a DMC-1300 board to control a servo motor used to sweep a mechanical
device through the beam on the CERN PS. I did the development work
at TRIUMF and created a suite of vxWorks functions to control the
device.
There was no point in creating any EPICS support since CERN would not
need it. However I used some glue logic in a subroutine record in
order to use DM as a GUI for TRIUMF tests.

I have a variety of vxWorks functions available including:

Create an instance of a device (can be used in EPICS)
control/status functions
execute single galil commands
download galil program files
download command sequences files
read back galil DPM.

Available at ftp://edevel9pc.triumf.ca/Misc/vx/  file galil.tar

A word of warning.

At TRIUMF I used an mvme162 running vxWorks and every thing worked fine.
I then spent about 3 week at CERN porting my code to LynxOS and CERN
Equipment Modules. CERN uses the CES 8062 (powerPC) and we had all
kinds of problems. We could not download long files without the PPC
crashing. I suspect some sort of vme bus timing violation at the 
galil end but we never got to the bottom of it. We recompiled for the
mvme147 which CERN were trying to phase out and it worked fine.
