Boost UltraSPARC T1 Floating Point w/ a Graphics Card?

alxtoth asks: "All over the web, Sun's UltraSPARC T1 is described as 'not fit for floating point calculations'. Somebody has benchmarked it for HPC applications, and got results that weren't that bad. What if one of the threads could do the floating point in the GPU, as suggested here? Even if the factory setup does not expect an video card, could you insert a low profile PCI-E video card, boot Ubuntu and expect decent performance?"
