No straightforward way I'm afraid[0]. It sounds like what you'd want is
a variation of "always" which doesn't move pixmaps out of video RAM for
fallbacks, which should be easy to add.


[0] With current EXA, you could plug in your own allocation/migration
logic via the CreatePixmap hook and friends, but that seems like
overkill here...
