 From what I can see there are several variants of the GTX460,
 some with the GF104 GPU, others with the GF114 GPU. There is no
 Quadro based on the GF114, but there are two mobile Quadro
 variants based on it: Q3000M and Q4000M.

 The GTX460 variants have the following device IDs:
 GeForce GTX 460		0x0E22
 GeForce GTX 460 SE	0x0E23
 GeForce GTX 460		0x0E24

 The corresponding Quadros have IDs:

 Quadro 3000M	0x0E3A
 Quadro 4000M	0x0E3B

 So you _should_ be able to modify your card into one of those,
 since the adjustment range is within the bottom 5 bits of the
 device ID and the GPU itself is the same.

 Q4000M looks like a closer match. I'd say it's certainly
 worth a try. :)

 I don't recall that virtualization is technically supported
 on the mobile series GPUs, but it might work just fine.
 Please report back whether it works if you try it, and
 perhaps add the model to the successfully tested passthrough
 GPUs on the wiki page. :)

 I'd still have a go at modding your existing card first, if
 for no other reason then because I don't think anyone has tried
 that particular model before.
