256 color) support on 24bpp displays

I'm trying to find the ideal settings/modes to run M$ Pinball Arcade, and I've
almost got it perfect, but I've run into a brick wall now. Generally, my
problems seem a bit worse than any others I've seen thus far...
My normal display is 2048x1536 24bpp on an AMD 64x2 3800+ machine with 1GB RAM
and an NV6800 card with the official binary driver, running Kubuntu Feisty (X
7.2.0, wine 0.9.31). Wine is configured to simulate a Windows 2000 install
with a virtual desktop of 1024x768, with hardware pixel shader support enabled.
If I run Xnest and request an 8bppmode, it refuses to start, claiming it can't
find the "desired default visual" (or something like that), despite a valid
8bpp mode being present in my xorg.conf.
If I run the game through VNC with just the right settings, I can get what
seems to be a normal 8bpp display, but the refresh rate is far too low to be
playable (maybe 10 fps).
If I run the game on a normal 8bpp xorg session with something like twm for a
window manager, with the default PseudoColor visual, the color map switches
when the game window gains/loses focus like it should, but the colors are
garbled regardless of what has focus, yet winecfg and regedit display their
colors properly when I try those in this mode.
If I run the game in that same mode, but without a window manager, the color
map never gets properly configured and I end up with a severely restricted
color set (maybe 8 or so colors and otherwise mostly black) in both winecfg/
regedit and in the game, regardless of what window has focus.
8bpp with Truecolor or DirectColor results in a black window/screen - pretty
much the same thing I get if I were to just run wine on 15, 16, or 24 bpp
(except that there is no message on the controlling terminal about not being
able to switch to 8bpp).
If I run the game in 8bpp with the StaticColor visual, I get what looks like a
7bpp screen (128 or so colors) but the game is otherwise playable. I can tell
that there are still too few colors by comparing against a real Windows box;
smooth color transitions are roughly twice as fine on Windows as on Wine, but
still clearly 8bpp.
8bpp with the StaticGrey visual gives me what looks like a full 8bpp 256-
greyscale screen (transitions between "colors" appear to be fairly smooth), but
I can't be 100% sure about this one.
