You beat me to it... :P

But to elaborate: the FPGA is basically a processor on a PCI card that
can be programmed to do anything. It's being created by the open
graphics card project so they can test their GPU designs. The cool
part is, they will be available for anyone to purchase. You could
program it to be a hardware version of yafray for your blender
animation and then turn around and reprogram it to do the DSP work for
a ladspa plugin. But of course... you have to have somebody write the
programs for it first, and writing programs for hardware is a little
different that writing software programs.

Read the section labeled "What is OGD?" from this article:

If somebody programmed libraries like FFTW to run on this chip it
could potentially offload a significant amount of DSP work.
