Older apt's were limited to about 200 chars, newer are about 1k chars and
the next version will be something like 32k give or take a bit. I don't
know what sort of limits dpkg has.

Not that I can think of. The | construct is not valid in a conflicts

Must be stated explicitly.
You have to be -VERY- carefull here because if you choose the wrong
sort of relations you will create a confliction loop involving dpkg which
is extremely bad.
libc6 conflicts with dpkg
dpkg pre-depends on libstdc++2.9
libstdc++2.9 depends on a new libc6
The only way this will work is if all version of libstdc++2.9 function
with the new dpkg and all versions of libc6 function with the new dpkg.
Oddly you might not be able to do anything with this, if you conflict with
all previous dpkg's then you won't be able to install dpkg or libc6 from a
