GOOD GUESS: I did exactly that (removed the two USB devices) and now the
PCI card works.

Now, how the heck can a USB device that isn't even active at the time
screw up the PCI device?

Note: when I went back to the stock 2.6.25 drivers the devices were
still plugged in, they just did not have drivers active. That would tend
to exclude weird stuff like ground loops (which would have still been
present).

Are you thinking an electrical level interaction (noise) or some
software level interaction?
