Do I have dual link?


I am the law!
I have a 1.5GHz 17" PowerBook G4 with a 128MB Radeon 9700 in it. I'm pretty sure I got it before the 30" display with the dual link requirements came out so I'm not sure if it has dual link or not. Apple's requirements page just say Radeon 9700 required, but I have a feeling that my 9700 isn't dual link.

Heres what system profiler has to say about it:
ATI Mobility Radeon 9700:
  Chipset Model:	ATY,RV360M11
  Type:	Display
  Bus:	AGP
  VRAM (Total):	128 MB
  Vendor:	ATI (0x1002)
  Device ID:	0x4e50
  Revision ID:	0x0000
  ROM Revision:	113-xxxxx-134

I suppose I could just bring it into the apple store and plug it into a 30" display and see if it works...
