The Virtex parts have 1 or more hard powerpc 405 or 440 cores
(dedicated silicon, not synthesized in the FPGA) attached to the FPGA
fabric. I believe they can run up to 400MHz.

Yes, the ML405 has a VGA port.

Xilinx provides a set of stock cores for common devices. Some of them
require licensing fees, some are free.

You can also use the stuff from opencores.org
