acpi=off does not help.
The sound card works ok with kernel 724, but no sound with kernel 741.

Yes ; I do not see any particular error message.
The identification of the sound card is correct. The only problem is
that ... i just do hear the so beautiful test sound !

Yes, no problem !

I do not see any significant difference concerning the sound card. You
can have a look at the corresponding sections of /var/log/messages:
When I start kernel 2.6.9-1.724_FC3:

When I start kernel 2.6.9-1.741_FC3:
