Howard, Andy, and I did our due dilligence on the OGD1 design to make
sure that it was really going to meet our needs.  To test that we
would be able to fit an OGA-compliant design into the ECP2-50, we
cobbled together a resource-equivalent "design" from pieces from old
designs we'd done in the past.  We blew the resource count by a
significant margin.  Our determination is that the 3S4000 is the only
chip available within the next 6 months that will meet our needs, so
we're switching back.

Have you used the Xilinx tools under Linux?  I tried it once, but they
require a kernel-space driver for the parallel port programming tools
(wtf?) and only offer it in binary form, and I believe they only
support RHEL.  I couldn't even get the driver to load under the
equivalent CentOS.  I only tried the free Webkit, since I don't have
the money for the full version, but I really didn't have any luck at
all with getting the actual device programming to work.
