Yup. Looking at that, I'm reminded there are four variables for
resolution: Height, Width, bits-per-pixel, and frequency (updates per
second).

The usual answer for how this worked was that you specified a particular
resolution at startup, and subsequent drivers looked up that resolution
in their own tables. There wasn't anything about passing a list of
resolutions in, it was _the_ specific resolution to use. The assumption
is that when you picked the startup resolution, that was the resolution
you intended to use, period.
