Well, as for the i-opener, I've gotten mine working.  See

I did not have a problem with a panic mounting the sandisk, I just
didn't have a /boot/loader on it so I couldn't load my mfsroot.gz.  I
was eventually able to find a Y-E Data floppy drive and use it as a
root filesystem by entering "ufs:/dev/da0" at the mount root prompt.
If a 4.0 kernel is on there, I don't know what to say, as I don't know
what worked at that point.  SuperDisk is certainly out of the question,
since it's not there even now.

Regarding USB drives, I have been using the Orb "2.2GB" USB-SCSI
version with some success.  There do seem to be some serious
filesystem corruption problems, but I haven't had time to determine
where they're coming from.  I often get corruption-related panics
while trying to install packages, and fsck always finds a number of
serious problems and removes about a dozen files (from /usr/lib
mostly, so I'll eventually lose something important).  When I
download something large, such as XFree86, the file's checksum
comes out wrong and gzip fails with errors.

I need to have a few hours free to try it on a different machine, with
different media, etc. to try to narrow this down.  I have also been
getting kue lockups, so there are a lot of possibilities.  I really
haven't played with the thing too much, partly because it's very
slow and takes a good 15 minutes to fsck every time I crash it.
