OK.

First, try the cvs version of the driver, you are still
using 0.2.3. I've fixed a Vertical Blanking bug there a few
weeks ago.

If the issue remains,

Keep your mach64/rage as the primary VGA device; you've set
your BIOS to initialise the mach64 first, and i guess that
your unichrome being non-Primary (and thus seeing different
BIOS initialisation), is why a bit in VBlank is set that
shouldn't be set, and that we're not handling ourselves.

Then put "832x624" as the only mode in your Modes directive
(in the Display subsection of your Screen section). And add
Option "PrintVGARegs" "True" in your Device section.

This, together with -logverbose 8, should get me a full
register dump.
