Well, if anyone cares...
I got NO respone in the TridiaVNC list either, but I did get an email
response from the author of x0rfbserver. Bottom line is that it's a known
problem and the author will let me know when it's fixed. (Thank you, Jens!)
Hopefully some other soul will find this message in the archives and save
themselves some time researching and/or waiting for an answer here...

Subject: x0rfbserver / xrc problem
Sorry if this has been asked before, but searching the archives for
'x0rfbserver' and 'xrc' both come up empty, although I know both products
have been mentioned here.
In a nutshell, I've tried both products on a RH 6.1 box with 8-bit video and
neither work. When launching, both give the following messages...
OXClient: Couldn't retrieve color #ffffe0
OXClient: Couldn't retrieve color LightYellow
OXClient: Couldn't retrieve color LightYellow
...which I somewhat expect due to the (lack of) pixel depth.
When connecting to x0rfbserver, the following is displayed on the machine
running x0rfbserver (I don't know what any of it means, but maybe it will
provide a clue for those who do):
framebuffer->width: 1024
framebuffer->height: 768
blockWidth: 32
blockHeight: 32
blocksX: 32
blocksY: 24
blocks: 0x80e4a48

When connecting from a Linux box, I see the following:
VNC server supports protocol version 3.3 (viewer 3.3)
Password:
VNC authentication succeeded
Desktop name "pb100"
Connected to VNC server, using protocol version 3.3
VNC server default format:
8 bits per pixel.
True colour: max red 3 green 7 blue 3, shift red 0 green 2 blue 5
Warning: Cannot allocate colormap entry for "grey"
Using default colormap and translating from BGR233. Pixel format:
8 bits per pixel.
True colour: max red 7 green 7 blue 3, shift red 0 green 3 blue 6
[The above line is different from the "default format" line.]
Got 8 exact BGR233 colours out of 256
Using 143 existing shared colours
With this I connect fine, but the display is, well, muddy at best -- the
colors are so muddled that if I didn't know what the icons and other items
were beforehand, I wouldn't be able to make them out.
I can connect to the same machine running Xvnc on display :1 and do not have
the same issue. When doing so from Linux, I get:
VNC server supports protocol version 3.3 (viewer 3.3)
Password:
VNC authentication succeeded
Desktop name "pb100"
Connected to VNC server, using protocol version 3.3

True colour: max red 7 green 7 blue 3, shift red 0 green 3 blue 6
[The above line is identical to the "default format" line.]
Got 8 exact BGR233 colours out of 256

>From another Linux box, I've tried the '-depth 8' and '-bgr233' options,
independently and together to no avail. From Windows machines, I've tried
nearly every combination of options vncviewer offers -- again, no joy.
When trying to connect to xrc, the screen starts to load and then fails.
The machine running xrc then shows:
Floating point exception (core dumped)
If connecting from another Linux box, I see:
VNC server supports protocol version 3.3 (viewer 3.3)
No authentication needed

Connected to VNC server, using protocol version 3.3
VNC server default format:
8 bits per pixel.
True colour: max red 0 green 0 blue 0, shift red 0 green 0 blue 0
[Is the above line causing the floating point exception, perhaps a divide by
zero problem? Just a WAG ;)]

vncviewer: VNC server closed connection
All of the machines I connect from are running 24 or 32 bpp video. If I
turn things around and run either x0rfbserver or xrc on my higher
pixel-depth Linux box, I can view it from Windows and my 8-bit Linux box
just fine.
Suggestions, ideas, etc. appreciated...
