Well, I did a little testing on my own and found that a way not to render
a machine unusable is the following (assuming bash 2.01.1-4.1 and libreadline 2.1-12
are installed).

dpkg -i --force-depends bash_2.02.1-1.4_powerpc.deb bash-builtins_2.02.1-1.4_powerpc.deb

it needs the force-depends because it needs the new libreadline.
But, if the libreadline is installed first the older bash does not work and dpkg fails at
postinst. Te newer bash works fine with the older libreadline.

After bash has been installed, test it (either login, or run it). Then, you
may install the libreadline debs:

dpkg -i libreadlineg2-dbg_2.1-13.2_powerpc.deb \
        libreadlineg2-dev_2.1-13.2_powerpc.deb \

The reason I did not experience the bash failure was that by pure chance maybe, I chose
this way to install it. All other combinations/ways I tried, produced effects similar
to the ones described in the list.
IMHO, the only safe way to get rid of such critical problems, is to have the
preinst/postinst scripts use another shell (maybe csh?)
Until I fix this and release another version, please use this method to upgrade.
