Hey list,
Here's how I managed to solve it
my $subr = $r->lookup_uri( $redirect );
$subr->add_output_filter( My::Filter::build_handler( $cgi, $messages ) );
$subr->run();
build_handler returns a sub which expects to be used like a filter.
This way I can build this sub with request-specific information for
altering the html generated by the subrequest.

Stephen,
Just a guess since I haven't done it, but maybe the input_filters
method would give you the Filter object you need?

Hi Mark,
The other pages on the site are not broken. I appreciate your
attempt to identify an underlying flaw, but that is not the case
here, and I am aware of the vagaries of html parsing (which is why I
leave it in the capable hands of HTML::FillInForm).
My question is how do I create a Apache2::Filter "object" to pass
into lookup_uri() when all the filter documentation i've seen
suggests that filters are subroutines. I'd love to be able to just
pass in a subroutine as the second argument to lookup_uri, but none
of the documentation suggests that as the way to go.

I have a form validator PerlResponseHandler (using

by the handler, but by other pages on the site. My
thinking is that I ought to be able to do a lookup_uri and
pass it a filter that can repopulate the html correctly,
but the online docs for filters is failing me. The
lookup_uri documentation says that it takes an
Apache2::Filter object, but nowhere can I find information
on how to create one of these. Whatever filter I build
I'll need to be able to pass into it data specific to the
parent request in order to repopulate the html form
correctly. How do I do this?
Have you considered fixing the "other pages on the site"?
Pattern-matching HTML that will then be subject to change by
other people on these "other pages" is going to drive you
crazy. Why not just make the forms do what they're supposed
to do?
