[Wine] Different Resolution in a Wine Window Possible?

[burpnrun]

I operate my openSuse 11.3/KDE desktop at 1600x1200 using ATI's CCC, but wish to run some Windows-based games in a Wine window at (say) 1024x764 while the main desktop remains the same (1600x1200).

Is this possible?  When I use windcfg and the virtual desktop setting, all it seems to do is change the SIZE of the wine window, but not the resolution.  TIA.
