Thanks. This wasn't my problem (read below), but your details got me
out of my "It's stopped working!!!! I DON'T want to have to think about
this!!!!" mindset :-)

The fact modules _were_ missing in my list, and the fact that "amidi -l"
crashed, let alone "amidi --dump" confirmed to me that the keyboard
_wasn't_ being initialised. So then I did what I should have done at
the start - cross check the Vendor/ProdID values given out
of /proc/bus/usb/devices against what was
in /etc/udev/rules.d/81-midisport.rules (as provided by the
midisport-firmware RPM). And, lo and behold, the Oxygen8 values weren't
pulling the values out of ye olde midisport_firmware 0.2 (I've confirmed
they're also in the 1.2 you pull directly from sourceforge) and manually
adding them to the rules file solved my problem.
So from that I can answer my own questions (plus some more)
* The old hotplug-based midisport-firmare releases (0.x) don't
work at all with Fedora 9
* It appears that you no longer need to separately supply the
firmware blobs - they're there in the 1.X series of
* The rules file included in the midisport-firmware RPM for F9
lacks most of the devices listed in the upstream package.

Once it's configured properly, the keyboard is working fine with the
126.96.36.199-1.rt3.2.fc9.ccrmart kernel. Don't know if it's relevant to you
or not, but if you were failing on earlier kernels it's worth a try
(note: as of right now all I've done is play the keyboard - no fiddling
with wheels or controllers - just notes).
Anyway thanks again for getting me thinking in the right direction.
