There's a few misconceptions in your understanding of the upgrade process,
which I'll try to address below. However, you're also using the wrong sequence
of events. You *first* want to update your kernel and base system, only then
your ports.

As such, freebsd-update cannot upgrade your kernel.

More likely to be bad queuing in the gateway or you're hitting the default
session timeout of 5 minutes of inactivity. See man ssh_config for
ServerAliveInteral and TCPKeepAlive.

This is out of sequence and likely the cause for some problems. First of all,
you must be sure that kernel.old is really a GENERIC 7.0-RELEASE kernel.
Secondly, this step /should/ have been run /before/ freebsd-update install.

Running an upgrade again, without a rollback is generally not a good idea.

Your world and kernel are out of sync, because of loading a not upgraded
kernel with a freebsd-update'd 7.2 world. I would try fetching the 7.2 livefs
ISO, mount it as a vnode and install the GENERIC kernel from there to get your
system back in working order.
Example steps:
$ sha256 /data/isos/7.2-RELEASE-i386-livefs.iso
SHA256 (/data/isos/7.2-RELEASE-i386-livefs.iso) =
4faa7b9d78d125f9b28521247e32e1f0bef3b0b0f21b654ba22c6e79ca3301ce
$ sudo mdconfig -a -t vnode -f /data/isos/7.2-RELEASE-i386-livefs.iso -u 0
$ sudo mount -t cd9660 /dev/md0 /mnt
$ sudo mv /boot/kernel /boot/kernel.bogus
$ sudo cp -Rp /mnt/boot/kernel /boot/
$ shutdown -r now # may need sudo if you're not in operator group
If you still have problems after this, it's likely you need single user mode
to get back into working order. Given the number of errors given by the second
freebsd-update upgrade command I wouldn't trust a freebsd-update rollback.
This would be where I'd restore the backups using a livecd and restart the
freebsd-update process, this time sticking verbatim to the handbook, but
skipping the "portupgrade test run".
