Well, I know 12.2(33)SRC has support for the L2VPN BGP 
address family feature:

lab(config-router)#address-family l2vpn vpls ?
  <cr>

lab(config-router)#address-family l2vpn vpls

We've, however, been advised to use BGP Autodiscovery in 
this release with caution, as the code still has a few more 
kinks in it that need to be ironed out. Depending on how 
long this takes to get fixed, we could consider using 
another vendor that has stable support for it already.

We didn't plan to deploy VPLS on our 7200's after we 
realized support was not included for this platform :-(.

Cheers,

Mark.
