I have no idea but from the arstechnica link below:

''VPU Recover is a "a patent-pending innovative software recovery feature
that enables the display driver to gracefully recover from graphics
hardware hangs. This feature also offers a direct feedback and bug report
mechanism and marks a major step towards crash-proof PCs." In theory, VPU
Recover will simply reset the GPU in the case of a critical error. This
should prevent system crashes, although in some circumstances you may get
dumped into a low resolution recovery mode not unlike that already
implemented in Windows XP (if you've seen it, you know it).''

And here's some marketing speak from ati:

>From my limited understanding it could be that the driver is "pinging"
the gpu and when it does not answer within a certain time-frame it resets
the hardware? But it seems it does not work on all radeon's so maybe it
needs hardware support as well? Ok, I'm only guessing...
