Inability of X server to switch resolutions isn't wine problem, ergo that
doesn't make a valid wine bug.

But note that this doesn't prevent wine from emulating e.g. 8bpp mode in
directdraw (that's done by inner conversion magic). This is not to say all
games will run, there certainly are bugs that affect some games, but this is
not at all different from 16bit or 32bit games. Unless there is substantial
evidence that multiple games are broken because of a single bug, they probably
all deserve proper individual reports, ideally with links to something
downloadable that can be tested. The mentioned fixme is NOT such evidence. All
8bpp games will print it on 24bpp desktop, but that says nothing about whether
they will work well or not.

This bug isn't good because it confuses newbies into thinking 8bpp mode games
don't run in Wine at all (which is wrong) and presents this as some kind of
single bug that affects all 8bpp games on all machines. In reality it's many 
issues affecting specific games. Please open separate entry(s) for specific
game(s) that doesn't run. See my previous comment for the kind of info that is
helpful for fixing this kind of bugs.

Info that is better suited for wine wiki imported to
http://wiki.winehq.org/ColorIndexMode. If you have experience running 8bpp apps
and working around related wine bugs, any enhancements to that article would be
appreciated.
