I've already got one wired up with Coy on my site. In my conf file: 
ErrorDocument 404 /perl/404-handler

[download]
and of course /perl is Apache::Registry marked. And at 404-handler I have: 
#!/usr/bin/perl -w
use strict;

print STDERR
  join (" ",
        map "[$_]",
        scalar localtime,
        "404 ERROR PERL",
        map { $ENV{$_} || "-" }
        qw(REDIRECT_URL REMOTE_HOST HTTP_REFERER)),
  "\n";
my $red_url = $ENV{REDIRECT_URL} || "?unknown?";

{
  local $ENV{HOME} = "/home/merlyn/lib/Stonehenge";
  require Coy;
}

my $haiku = Coy::with_haiku("URL $red_url not found");
for ($haiku) {
  s/&/&/g;
  s/</&lt;/g;
  s/>/&gt;/g;
  s/^\t/&nbsp;&nbsp;&nbsp;&nbsp;/gm;
  s/ /&nbsp;/g;
  s/\n/<br>/g;
}
(my $red_html = $red_url) =~ s/[\x00-\x20"<&>"\x80-\xff]/&\#@{[ord$&]}
+\;/g;

my $tp_link = "";
if ($red_url =~ /^\/~/) {
  for ("http://www.teleport.com/$red_html") {
    $tp_link = <<"DQ";
<p>Perhaps you were looking for something at Teleport's web-server,
such as <a href="/cgi/go/$_">$_</a>?
DQ
  }
}
print <<"DQ";
Content-type: text/html
Status: 404 Not Found

<head><title>File Not Found</title></head>
<body><h1>File Not Found</h1>

<p>$haiku
<p>The requested URL $red_html was not found on this server.
