As far as I understand, these are all fairly simple (by today's standards)
serial boards, so the assumption is that anyone running a machine with
a 2.6.35 kernel would get a $5 (more for mulitport) USB serial adapter.

Ok, good to know, this is the kind of information I was looking for.
I agree that as long as there are users, we shouldn't just kill the drivers.
For rocket.c, Alan already mentioned that there users left, so it's not
going away.

Note that there are also cases where we know that users exist, but for some
reason they are all stuck on 2.4 kernels or older anyway, so there is no
point in keeping the driver for new kernel releases. Also, we can always
add them back if the situation changes or we hear of users we didn't
know about.
