You should not have neede to run alsaconf on fc4, it should have found
your card automatically...

Try with this for the soundcard options:

alias snd-card-0 snd-ice1712
options snd-card-0 index=0
options snd-ice1712 index=0

That should be all you need.

This is all very strange. 
What do you have in:
  cat /proc/asound/cards
  cat /proc/asound/devices
If you don't have anything there then alsa is not started. 

If you appear to have things there try starting "envy24control" to make
sure it can see your card. 

Then start (from the command line first) jack:

  jackd -R -d alsa -d hw
