12.0(10)ST, if you have it, runs LDP.  But if you have it, you
probably knew that already. :)

A cisco router which speaks LDP can also speak TDP.  So yes, if you
have some boxes running TDP and some running LDP, you can interoperate 
by configuing one, or the other, or both, on a per-inteface basis:

gsr11(config-if)#mpls label protocol ?
  both  Use LDP or TDP (Adapt to peer on multiaccess interface)
  ldp   Use LDP
  tdp   Use TDP (default)

If you configure 'mpls label protocol both', the bias is towards LDP.

Until you get 12.0(10)ST or 12.2(x)T (where x is probably 1 or 2), you 
can't run LDP at all.
