Everything. I was able to install the game from installation CDs successfully, patch it and play, all from Wine.
What does not
The game initially failed to start in a wide screen mode but this is not specific to Wine as the same issue occurs on Windows. After reconfiguring the game to use the correct resolution using FPS Optimiser (http://www.fileplanet.com/hosteddl.aspx?/planetelderscrolls/fms/files/mods/1188/morrowindfpsoptimizer196.rar) it started fine.
What was not tested
3rd party mods.

About windows getting minimized, the workaround is pretty simple : the MenuStates of the .ini file is reset everytime you launch the game, which causes it to define minimized windows. What you need to do is chmod it to read-only (chmod 444 does the trick) after having changed the MenuStates parameters to suitable window sizes.
I got it to work with around 50 mods, the thing is the .ini file needs to update the modlist, so you first need to run Morrowind with a writable .ini file (chmod 644 works like a charm), then you can kill the process immediately afterwards (wineserver -k after Ctrl+Alt+F1 for instance), chmod the .ini to 444 after checking the MenuStates section is still well and about, and launch the game !
