No Actel Igloo that I know of supports PCI-e in any shape or form. If
act, I'm not sure what Actel FPGA supports any form of multigigabit
serialization.

Consider looking at Altera Arria GX, which is in production, or Arria
II GX, which will be in production in the near future.

Your statement that Spartan-6 has only two lanes is incorrect;
although the integrated endpoint only supports one lane, there's
nothing stopping you from using all 8 transceivers in the design for
an 8 lane link. It just means you need to do a bit more work.
