cg6s are not all created equal.  It would not surprise me if the
onboard cg6 were not capable of 1152x900x66, or perhaps even incapable
of switching scan frequencies at all.  (This may not even be common
across all IPXes; I don't know whether different IPXen have been made
with framebuffers of different capabilities.)

My guess is, yes, provided you don't actually power off.  Maybe even if
you do; I suspect that setting is actually stored by the framebuffer
itself rather than NVRAM, though I've never investigted in any detail.
