With the permission from the author (a QSS staffer), I am pleased to announce the QNX4 driver for VMWare, available here. The package includes a graphics driver for Photon and a vmtool for accessing VMWare information (date, clipboard, etc.)
Unpax and follow instruction in the README file. In addition to the README instruction, setuid Pg.vmware and run crttrap clear.
The author might release this on developer.qnx.com if time allows (they are all very busy working QNX 6.3).
This is unsupported, but if you run into problem email me and if I can't help I'll forward your info to the proper person.
Expect a QNX6 version soon.
