OK, so for i386 (or other VGA h/w) users who want DDB and X, why not
compile in rcons-style software-blit tty emulation, and have DDB use
that, rather than VGA hardware text modes?

(At some point the kernel would have to check whether VGA h/w is in
text mode or graphics mode, but the X server can tell the kernel that
when it starts and exits. I guess "VGA" really includes EGA, MGA,
(PC-weasles?)  etc.,-- whatever XFree86 supports.)

Am I missing somthing obvious? Apart from the code bloat?
