pfLightPoints and RM's

I have an application in which I turn on a big bunch of pfLightPoints
(the usual runway lights, etc.). These points render as expected on
a PowerIndigo 2 Extreme, and a few Onyces I have tried it on. These
Onyces always have more than 1 RM4. The application messes up in a
big way on the single-RM4 Onyx on which I need to run (adding an RM4
makes everything work great again, so I think I have narrowed this
problem down to the single RM4).
Instead of light points I get huge rectangles (spanning some 80%
of the visual field) and performance goes to hell (0.5 frames per
second appx. compared to 30 fps even on the extreme).
My question is 2-fold:
1) what do pfLightPoints use the RM4 for?
2) is there any way I can maybe give up some rendering beauty for
the light points and run my app anyway with 1 RM4? (the quality
of the light points is much better on the stuffed Onyces, but the
quality of the Extreme light points is perfectly adequate for my
purposes).
Thank you very much.
Carlo.
