We're using VESA modes only during startup, so the modes shouldn't be 
that off.
Have you tried to switch to different modes with the VESA drivers on 
these chips?

I would rather like to find out why it is failing for you before doing 
such a step.
This would especially be of interested of those needing to use the VESA 
driver. If some chips are known to have a broken modelist, we might 
want to blacklist them.
Maybe we just choose the wrong mode option of several, though, as the 
chips are definitely capable of producing that resolution (and VESA 
modes should always come out with 60 Hz).

It just looks so much better to use the native resolution.
