You'll probably need Alexandre's comment on this, but it doesn't look 
correct to me.

Querying the X server for the key state on each call to GetAsyncKeyState 
bypasses the input queue, and is likely to cause applications that poll 
GetAsyncKeyState to slow down...

This is likely to be a tricky problem to solve, as you need to run 
Wine's X11 message loop, but Wine currently only does that when the 
application waits for input.
