Seems like the bad old days when we saw lots of total host lockups on
cold resets, etc.  I didn't see anything useful in the logs, and I was
running lockdep enabled kernel.

Since WLE900VX works for me, I've little interest in hacking on the
Sparklan NIC.  Possibly it's just a bad beta hardware or something like that.

If you have trouble getting a hold of this NIC, I'll be happy to mail
it to you.
