My /etc/modprobe.conf is exactly the same:
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && 
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-remove snd-intel8x0

The only error message I can see in /var/log/messages (and clear related 
to kernel 2.6.10-1.741 is the following:

Jan 17 07:24:23 dc4u kernel: PCI: Using ACPI for IRQ routing
Jan 17 07:24:23 dc4u kernel: ** PCI interrupts are no longer routed 
automatically.  If this
Jan 17 07:24:23 dc4u kernel: ** causes a device to stop working, it is 
probably because the
Jan 17 07:24:23 dc4u kernel: ** driver failed to call 
pci_enable_device().  As a temporary
Jan 17 07:24:23 dc4u kernel: ** workaround, the "pci=routeirq" argument

I tried to restart the new kernel with the pci=routeirq argument, but it 
does not work better.
