You have to keep the name space of a bridge clear, so I would inline the curry_method function (alternatively, you could keep it in some other namespace). However, here's a simple case demonstrating that slurping @_ works: 
$ perl -MCGI -e 'sub curry_method{ my ($o, $m) = @_;
                                   sub { $o->$m(@_) } }
                 $c = CGI->new;
                 $p = curry_method($c, 'p');
                 print $p->("Hello World"), "\n"'
<p>Hello World</p>

You make a good point about having a closure for every method of every instance of the bridge class. Its a little extra space for a little extra simplicity. I prefer simplicity to speed/space in this case.

The doubled $obj in @_ only occurs if you are calling the thing like a method twice. Once the object is curried, the method becomes a plain old function. I envisioned something like this (untested): 
package Bridge::Simple;

use strict;
use Carp;

sub new {
    my ($class, $obj, $mapping) = @_;
    my $self = {};
    @{$self}{keys %$mapping} =
          map { my $meth = $_;
                sub { $obj->$meth(@_) }
              } values %$mapping;
    bless $self, $class;
}

sub AUTOLOAD {
    my $self = shift;
    our $AUTOLOAD =~ s/.*:://;
    croak "no method $AUTOLOAD" unless exists $self->{$AUTOLOAD};
    goto $self->{$AUTOLOAD};
}
