i'll have a beer with you if i meet you at networker's :)

two slight changes:

interface ATM5/0/0.43 point-to-point
 description Pedro [11th and Fairview or somewhere near] 640kbps
 ip address 216.173.208.233 255.255.255.248
 no ip proxy-arp
 atm route-bridged ip
 pvc pedro 1/43
  ubr 640
  ecapsulation aal5snap

please restore ip route-cache and ip mroute-cache on the config. some
suggestions. RBE is also available for the 7200. and if you do go with the
7500 solution, please be aware that 12.1(5)T / 12.1(5)T1 is not supported
for VIP2-40s and lower currently. we hope to restore support for
VIP2-40s and lower shortly.

regards
