Runs great on Vista.
It installs fine; to run it, to get past bug 21790 by doing 
'winetricks vcrun2005'.

The next problem is a crash related to
d3dx9_36.D3DXAssembleShaderFromResourceW,
roughly bug 12020.  Work around this with 'winetricks d3dx9'.

The next problem is that full-screen mode doesn't work (bug 21791).
Work around this by telling the game to run in a window.

Press Enter to start the game.  When it starts, press and hold the
left or right arrow key.  The ball will sweep across the court to the
end; switch keys and continue sweeping in the other direction.
On Vista, motion is smooth.  On Wine, there is a big pause exactly
once per second.

This was tested on Jaunty on a quad core (and Vista on a dual core),
both with nvidia 8500 cards, and with latest proprietary driver on Jaunty.
