Not all old modules, just the old site_perl/i686-cygwin XS modules.
The others can happily co-exist.
You can also install both perl versions in parallel.
The only conflict is /usr/bin/perl.exe and some scripts in /usr/bin/

Simply install one and then manually extract the other favored perl, like
  tar xfj ...down/http..../release/perl/perl-5.10.1-5.tar.bz2 -C /

A full reinstall of my ~1000 cpan modules required 2x perlrebase.
Not that much hurt as with 5.10.

Hack your /etc/setup/installed.db and fake the latest perl version. Be
sure to have a backup patch.
grep perl.*5.10.1 /etc/setup/installed.db
