Joe,

What is in your modules configuration file?  Does Fedora use 
/etc/modprobe.conf or /etc/modules.conf?  Anyway, you might try defining 
these two devices with aliases that set them up so the Radium comes out 
as MIDI #1 and Audiophile as #2, that way any application that by 
default looks to interface 1 for input won't need to be patched in 
through aconnect or qjackctrl to see the Radium.

I believe snd-usb-audio supports up to 8 devices, so you should be able 
to define the 2 you are using to control the order in which they appear 
on your system.

Something like:

alias snd-card-0 snd-usb-audio
# M-Audio Radium 61 (see *** below)
options snd-usb-audio vid=0x763 pid=0x1110 index=1
alias snd-card-1 snd-usb-audio
# M-Audio Audiophile 2496 (see *** below)
options snd-usb-audio vid=0x763 pid=0x1110 index=2

*** note - the vid and pid above are for my midisport 2x2, but if you "cat /proc/bus/usb/devices" you will see the vid and pid for your two devices.
