I doubt there is. DJGPP Bash uses direct hardware access, AFAIK,
i.e. its whole method of output it 100% different from the Unix-like
'terminal' interface. That's the same reason that already keeps
Windows NT from scrolling DJGPP Bash's text output. It's also one of
the main reasons why DJGPP Bash's text output is a whole lot faster
than Cygwin's one.

For other programs to be able to capture and scroll its output, you
need a Bash port like Cygwin's, which uses a simulated 'terminal'
(i.e., ANSI.SYS-style output, and an inboard ANSI.SYS-like driver) to
access colored text and cursor movement. At the very minimum, you'll
have to 'set TERM=xterm' or similar, before starting Bash, and have a
Bash that resects that setting.

OTOH, the problems you talked about with using Cygwin's rxvt seem to
stem elsewhere. Those bash sessions weren't being properly initialized
(missing $HOME, no /etc/profile, and such...), to begin with.
