With a machine that has a native VBE mode for the panel, the problem is
that clock computed from the hardware settings is not quite the same as
the clock requested in the mode. I think the clock computation must be
slightly off, but even with that fixed, it will probably not quite
match. I think we'll need a magic flag in this mode telling DRM to allow
a bit of fuzz in clock matching.
