Actually, I can't say for sure.  I haven't been using the wire in a
while, but I thought I remembered that it did.  At the very least it
doesn't hang a resume.  In case it matters, I have the driver compiled
directly into my kernel (it's not a module).

It seems to work fine.  I actually used S4 instead of S3 for a while
(because S3 didn't work).  It's obviously a little slower than S3, but
that's not a big deal for me.
