Coming soon to the NVIDIA driver will be the ability to use PCI-E MSI 
interrupts
on platforms that support it.  While this won't solve the problem of a CPU
being pegged with a stuck USB controller interrupt, it will at least prevent
the nvidia graphics driver spending most of its time handling interrupts.
