IPB2 + 4670

[Varava]

Hello
Im trying to crack IPB2 hash with HD4670.
But this is what im getting:

Hashes: 1

Unique digests: 1
Bitmaps: 8 bits, 256 entries, 0x000000ff mask, 1024 bytes
GPU-Loops: 32
GPU-Accel: 40
Password lengths range: 1 - 15

Watchdog: Temperature limit set to 90c

Device #1: Kernel ./kernels/4098/m2810_a3.ATI RV730.64.kernel (413772 bytes)

Is this card supported with IPB cracking or im missing something?
Thx
