Did you ever try this in practice?
I just cannot make it work.
What parameters to text2pcap do you use?

Try 'debug ip packet dump' (undocumented, sadly), and the following Perl 
script:

--------------- Cut here -----------------------

#!/usr/bin/perl

# Convert Cisco dump file format to something text2pcap can read.

sub dumppkt () {
     for ($i = 0; $i < scalar(@pkt); $i++) {
         if ($i % 16 == 0) {
             printf "\n%08X", $i;
         }

         printf " %02X", $pkt[$i];
     }

}

while(<>) {
     chomp;

     unless (m/[0-9A-F]{8}:/) {
         $new_pkt = 1;
         dumppkt;
         undef @pkt;
         next;
     }

     # Strip the offsets and ASCII dump
     $hex = substr $_, 10, 35;

     # Remove all spaces
     $hex =~ s/ //g;

     # Convert hex bytes on this line
     while ((length $hex) > 0) {
         push @pkt, hex (substr $hex, 0, 2, "");
     }

}

dumppkt;
print "\n";

--------------- Cut here ------------------
