Can one debug 32-bit x86 images with an x86_64 gdb?

We are starting to port our 32 bit product to an x86_64
platform (RH 4.0 beta2). Once we have it running as a
32 bit image (still compiled with gcc 2.96) we will start
the slog to gcc 3.x and a full 64 bit port.
Except for the 32 bit gcc which we have had to migrated
-- our code currently includes numerous anachronisms no
longer accepted by the 3.x compilers -- we have been able
to coax the native system tools (bison, ar, ld, etc) into
compliance with our 32 bit build procedure.
Debugging is a different story. The install gdb image
describes itself as:
It does not decline to debug our 32 bit images yet it
produces total garbage. Is there a flag or environment
variable that I may have overlooked? Or is a single gdb
image not intended to fulfill both roles?
