It's the "trying random RGB values" part that I would consider broken. It
should "just work", but without pallete-switching, it won't.

Well, if you consider the "restricted" color in 8bpp, more power to you.

Do you have a NuBus video card? If not, the LKM or SLOTMAN kernels are
completely useless. Michael Zucca is supposed to be getting close to
releasing an INTVID2 test kernel, tho (of course, I can't promise anything
for him :-) and this should give you pallete-switching support on internal
video (although I don't think that it will support all machines when it
first comes out).
Later.
