If ddx is newer than the kernel than we should not write the mpos reg.
I think the issue is more about how mesa knows that ddx is recent
enought. Mesa driver need to check before enabling those that ddx will
restore its mspos settings. Others solution is to always restore for the
ddx the mspos settings (mesa stills need to check for kernel support).
