AFAIK TOS 4 use either VDI or LineA to blit the Fuji to the screen.

Exactly, that's why it should be possible to first open the physical
workstation (if not already open, but Julian is probably right when he
says it isn't), and then use the handle to the physical workstation to
open virtual workstations. I.e. there's no need to use graf_handle() to
get the handle to the physical workstation.
