disclaimer: I know next to nothing about PCI.
As some of you might already know, Lattice provides a few "free" and
open-source IP cores. One such core is a PCI controller for XP (our
smaller FPGA).

While I am sure it is "bloated" and probably useless in an ASIC (and the
EULA requires you to use it with lattice parts only), it might serve as a
good reference design for OGD1. Furthermore, some of the gurus on
comp.arch.fpga has stated that this core is much nicer than the open
source one on OpenCores.org, but I really cant tell as I have tested
neither of those.
So if anyone cares to setup a testbench, we could test our PCI controller
against theirs (and OpenCores). I would do it myself, but I recently have
come to accept that I am too dumb for hardware design ;)
BTW, in case anyone cares, lattice also have a popular microcontroller
called Mico8 under GPL. Nothing that boots Linux, but if you liked the PIC
line, you will love this one :)
