hi,
we set up a 1941 with c1900-universalk9-mz.SPA.151-4.M3.binand tried to bring up
EHWIC-3G-HSPA+7 in the vrf.
config:
chat-script gsm "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
!
ip vrf #99
description internet
rd 10.1.1.1:99
!
!
interface Cellular0/0/0
ip vrf forwarding #99
ip address negotiated
encapsulation slip
dialer in-band
dialer string gsm
dialer-group 1
async mode interactive
!
ip route vrf #99 0.0.0.0 0.0.0.0 Cellular0/0/0
ip route 0.0.0.0 0.0.0.0 Cellular0/0/0
!
dialer-list 1 protocol ip permit
!
Result:
Router#ping vrf #99 4.2.2.2
% VRF #99 does not have a usable source address
Router#
Router#ping vrf #99 4.2.2.2 source cellular 0/0/0
% VRF #99 does not have a usable source address
Router#
if we move the cellular 0/0/0 to GRT
Router(config)#int cell 0/0/0
Router(config-if)#sh
Router(config-if)#no ip vrf forw #99
Router(config-if)#ip addr nego
Router(config-if)#no sh
Router(config-if)#end
Router#
Router#ping 4.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 68/72/84 ms

Is this interface not supported in vrf setups?

Hello Markus,
there is nothing listed in HWIC configuration guide
see
However, the cellular interface is an asynchronus interface ( async mode interactive) and my guess is that this the reason why VRF is not supported on it.
For example for correct support on ISDN BRI or PRI interfaces the command dialer map vrf aware had been introduced.
http://www.cisco.com/en/US/docs/ios/dial/command/reference/dia_d1.html#wp1013440
I had the same symptoms with BRI or PRI interfaces
Hope to help

With the older 3G card the setup is supported, maybe I have to raise an TAC case

Did you remember to create the layer 2 VLAN?

please refer to design at http://www.cisco.com/en/US/docs/solutions/SBA/August2012/Cisco_SBA_BN_VPNRemoteSiteOver3G4GDeploymentGuide-Aug2012.pdf
You should configure cellular interface and Dialer as well, but as dialer pool.
This worked for me.
The config should be like this:
interface Cellular0/0/0
no ip address
encapsulation slip
dialer in-band
dialer string gsm
dialer-group 1
dialer pool-member 1
async mode interactive
int Dialer1
ip vrf forwarding #99
ip address negotiated
encapsulation slip
dialer pool 1
dialer idle-timeout 0
dialer string gsm
dialer persistent
