According to Alex in #437332: "multi-head is handling is not really
working properly at the moment due to a lack of documentation on the
XPRESS chips".

So it looks like the driver isn't working that bad on your kind of Xpress :)

Can you try with a DVI monitor, or another monitor, or another
resolution and refresh rate?
