No, I don't, and I don't have a USB hard drive either. I do have a USB DVD
drive, and a machine which can boot an Ubuntu install CD from it. But this
is transparent to the installer up to a point; it doesn't know that it's
been booted from a USB device until it tries to mount it.

No, and I wouldn't be inclined to try, given the throughput and latency.
Unlike USB, though, this is trivial to change; it's just a matter of moving
the firmware from /usr/lib/hotplug/firmware to /lib/firmware.
