I have the same problem with an IBM Thinkpad R40 and a HUAWEI E630 PCMCIA modem.

Ubuntu 9.04
IBM Thinkpad R40 1Gig Ram
HUAWEI Model E630 Mobile Connect Modem (3G)
Service Provider - VODACOM (South Africa)

Ubuntu hangs after trying to make a Mobile Broadband connection.
Completely hangs. The only way to recover is to turn the laptop off.

I have found that you can connect successfully by doing following.

1. Remove the modem from the pcmcia slot.
2. Turn the laptop on and wait for Ubuntu to complete booting.
3. Turn off wireless networking.
4. Turn off networking.
5. Insert the modem into the pcmcia slot.
6. Wait for Ubuntu to find the device and load the drivers.
7. Enable networking.
8. Wait for "NETWORK - You are now offline" message.
9. Select to connect to the broadband connection.
10. Wait for "GSM - You are now disconnected" message
11 Select to connect to the broadband connection again
12 You should get "GSM - Connection established" message.
