Not entirely true.  It's a function of your video BIOS, not of the vesa
driver.  The vesa driver can only set modes that are listed by the video
BIOS, but it does know how to query the monitor for supported modes, and
will attempt to set the monitor's native mode if it happens to be
exposed by the BIOS.

The X log you provided elsewhere in the thread seems to say you're not
using the vesa X driver though:

That's the fbdev X driver, pointed at either vesafb or uvesafb kernel
driver.  Which I suppose will get you a high-res console, but isn't
especially great for mode selection in X.  (The fbdev interface has no
way to query the kernel for supported resolutions, so X can't even know
what to ask for.)  If you stopped using vesafb you might have a better
time of it.
