Geoff,

Like previous posters have said. Make sure the IP address is still on
the interface.
Your config should look quite similar to this (perhaps some interface
names are different):

R1
!
ip vrf TEST
  rd 10:10
!
int fa0/0
  ip vrf forwarding TEST
  ip address 192.168.1.1
  no shut
!

S1
!
ip vrf TEST
  rd 10:10
!
int fa0/1
  no switchport
  ip vrf forwarding TEST
  ip address 192.168.1.150
  no shut
!

Then it should just work when you issue:

R1: ping vrf TEST 192.168.1.150

S1: ping vrf TEST 192.168.1.1

To make sure the switch supports VRF-lite, ensure you have the correct
SDM template selected.
When you enable VRF it already states which image you need. At least
the 'routing' template supports it.
You should have no issue when only configuring R1 though. You can test
this independently.

To change the S1's SDM template issue this in configure mode:

S1: sdm prefer routing

Then save and reload the switch.
