It was a long time ago that I stopped using Photoshop so my memory is a little
fuzzy on exactly how I set it up but I did have this working at one point.
Since that time I have reinstalled my system several times including wine so I
can't check out the installation to figure out the exact details.

Wine is not a VM and does not function like one.
It is possible to run the windows control panel in wine (wine control.exe)
and it comes with some basic control panel applets out of the box. But wine
does not have the CM control panel applet as part of the base installation.
But on older versions of window (XP and older) this was not included with
Windows either. So installing and running the Windows XP CM control panel
applet should be possible.
In addition I think all the CM control panel applets does for things like
display profiles is to create registry entries so even without a working CM
control panel applet it should be possible to hand edit the registry to set
this up. Not very user friendly and it requires an understanding of how
Windows uses the registry for CM. I wasn't claiming that it was user friendly
only that it was possible.
