Ok, so I finally got a few minutes to boot into FC2 at home and try this
out. This solution works for me and should (I think) for you (remove the
section you have in /etc/modprobe.conf that says it was generated by
alsaconf, it is not needed):

After this line:
alias snd-card-0 snd-emu10k1
Add this line:
options snd-emu10k1 index=0

Then add these two lines before the "alias usb-controller ..." line:
alias-snd-card-1 snd-usb-audio
options snd-usb-audio index=1

This is telling the alsa subsystem to always load the usb driver at slot
"1" and the Emu card at slot "0" (the first one). Seems to work fine
here with my laptop and an external midi keyboard that has a usb
