I personally have no experience with that GPU, but others might. Theoretically, yes, it should work, as long as it has Pbuffer support, but the performance is another matter entirely. It's often the case that reading back the pixels is more the limiting factor in a multi-user situation than actually rendering them. Some hardware, namely NVIDIA, doesn't scale well when doing pixel readbacks unless you use PBO's (which can optionally be enabled in VirtualGL 2.2.)
