I don't know a single thing about the VTX.

I think that RE2 is supposed to just work on the KONA backplane set up
for IR. I don't remeber hearing that KONA-RE2 machines required
anything other than a swap of the GE, DG, and RM boards to upgrade to
KONA-IR.  However, for piece of mind, the guys at 
http://www.gisparks.tas.gov.au/sgi/OnyxRealityEngine2.html
should be able to answer your questions definatively.
