Hi,

I'd like to dredge this one up again, since it's been a couple months
and I still run this patch locally. =)

It does hurt measured performance, but for the broken set of boards
this is absolutely necessary to function on a Gigabit link and it
doesn't look like this broken set is really a minority given the
number of complaints I've seen.

Thanks,

Kyle Evans
