"Can't create the colourmap"? That sounds like it requires PseudoColour,
ie. a palette-based display. So -cc 3 would be right. Try using the
vncviewer in 16-bit mode, which might be easier for Xvnc to convert to from
PseudoColour mode.

Well duh, because the rendering method is the same in each case because
you're always running VNC. What I meant was if you were running it on a
physical display it might have access to hardware acceleration features
which could speed it up tons. This is especially the case for applications
which like to have OpenGL available, even if it isn't an absolute
requirement.
As an example, consider the two G3-based Macs I have. One is actually a
6-year-old PowerMac 8100 with unaccelerated video and a CPU upgrade, the
other is a proper PowerBook G3 with a Rage128 video chipset. The graphics
performance of the PowerBook is an order of magnitude greater, despite the
two machines having identical CPUs and large L2 caches.
For a slightly less wild example, VNC on my P166/MMX Linux machine
sometimes crawls, especially if I leave a screensaver active by mistake.
The native X server performs much better, despite the ageing video card
involved (a Matrox Mystique or, more recently, an even older Cirrus Logic
5430), simply because video acceleration *exists* and much work can be
handed off to the hardware.
This is why I suggest trying x0rfbserver if you can't get Xvnc to perform
adequately for your needs.
