Exactly!  I've had machines where the on-board hme negotiated properly,
but an Sbus hme (or combo card) wouldn't - talking to the same switch!
I've never had a problem with 100Mbit qfe cards - but have a 10Mbit quad
card that sometimes has to be un-plumbed and re-plumbed when the cable is
unplugged!  Argh!

And I have gotten that weekend phone call from former clients who moved a
machine to a new data center and switch who forgot to look in /etc/system
and got burned by auto-negotiation problems... ah, well.  We call that
"job security..."

What's funny, though, is that nearly all those problems I described above
were with a Cisco Catalyst 5000 - but the same interfaces plugged into a
3548 worked just fine!

Over on the NetApp toasters list folks are still running into problems
with duplex issues - things "appear" fine at first blush, but NFS
performance sucks; lo and behold, it's a bad switch or a cranky interface
or someone tweaked the startup files to hardwire a port...

So, I agree with Caspar, certainly no one vendor is to blame.
