Yes. There are other ways to find out that the game lost focus, e.g. by
listening to WM_ACTIVATEAPP messages or checking the d3d state after
IDirect3DDevice9::Present. Games can in practise use way A to detect focus loss
and way B to detect focus regain.

Unfortunately d3d9 cannot separate those two cases. In both cases the window
manager tells us that we have lost focus. The message wined3d receives is the
same in both cases.

You could consider filing a feature request with xfce to request better
isolation of workspaces and e.g. keep track of the foreground window per
workspace rather than per X server. But this again has problems. E.g. games
throttle their framerate on focus loss or pause the game, which may be intended
behavior. I suspect the xfce devs will just tell you to run two X servers, as
this will also take care of resolution differences.

Also the situation with the Linux games I tested on kde is a lot worse: With
etracer or ut2004 running I can't change workspaces at all.

This is just another partial workaround, but it may help in a few more games:
Some games are just happy with the existing 1920x1200 resolution if it is the
only supported resolution. You can achieve that by setting UseXRandr and
UseXVidMode to false. See http://wiki.winehq.org/UsefulRegistryKeys for more
details. Of course this only works in some games - others just crash when they
can't get the resolution they want.

Also I think using xrandr (or any other tool) to pre-adjust the X server's
resolution before starting the game. I'll try this after my wine compile is
finished.
