[nsp] VLAN configuration question

Hi,

	I need some assistance with a thorny networking scheme I'm
trying to implement.  Here's what I'd like to do:  I have two Cisco 3640
routers separated by a T1.  I want to set up a split-subnet VLAN on the
ethernet side of these routers.  See diagram.  The problem I'm having is
that the switch on the 3640(2) side of the connection is an unmanaged
D-Link with no VLAN capability.  Can I somehow perform this feat with my
setup? Would it be possible to have the 3640(2) router encapsulate data
(based upon MAC?) for the 10.30.50.100-103 machines and send across the
T1 link?  Ideas?  Thanks!

		          s1/1 10.30.1.2/30		       s1/1
10.30.1.1/30
	
3640(1)----------------------T1---------------------3640(2)
		  | fe0/0 10.24.50.1		           | fe0/0
10.30.50.1
		  |				           |
		  |				           |
	     Catalyst 3750			        D-Link
		  |				           |
		  |			 	           |

	  10.30.50.100-103 			   10.30.50.0/24

            (VLAN on cat 3750)

Note also:  the catalyst 3750 is sitting on physical subnet
10.24.50.0/24.
