The Radeon driver has hardware acceleration, the Vesa driver does not.
So, using the Vesa driver, your performance will suck. :)

I never got the Radeon driver and the Radeonfb driver to play nice
together, so I can only say "same here."

No, it should be detected correctly.

1600x1200, probably, but you should use the one that is the native
resolution of the panel. Anything else will be either scaled or with
borders.

...and now, show at native size, with borders.

Benchmark, since it depends a bit on your applications, but the
performance difference is pretty small these days. Occasionally, like
for 3D stuff, you may find 16 is actually slower than 24, but I don't
know for this specific hardware.
