It seems pretty unlikely that you'll be able to mine using an integrated graphics card (at least in the short term). The major video card manufacturers tout their CUDA/OpenCL technology as features, so they wouldn't want to let everyone use it (especially Nvidia's CUDA).
As for the Quadro FX 3000, it cannot use CUDA because CUDA was first implemented on the G8x cores (think Geforce 8000 series), while your graphics card has a NV35GL core (equivalent to a Geforce 6000 series). Thus, your card is not CUDA-compatible. OpenCL came to Nvidia after CUDA, so there's no hope there either. Sorry about that.
You could try to get a very cheap, used Radeon 5770/6770 (it's the same card) and crunch out 200 Mhash/s. They're also good for moderate gaming, if you're into that.
