I have encountered exactly the same problem on PAL. It has been reported to 
SGI (Switzerland) without anything happening yet. 
*workaround*: 
Do a quick switch to the standard (console) 60 HZ video, define your color-
map, and go back to NTSC. The colormap is apparently written only if 
you are in standard video mode. The switching proves to work with 
home-made software but is certainly not applicable if you don't have 
source on hand.
