This seems to clear up a similar/identical problem we had on our
hardware, but haven't had time to investigate. Good work, thanks!
I'm attaching a patch against CVS (last synced on the 10:th of December,
since the sourceforge server seems to be down as usual - but I don't
think that file has been modified) for others testing on other
boards/chips, since I only have 1550 hardware here.
