Sometimes it's possible to unbind devices, but I never experienced a
serious difference between a simple set up machine and a special tuned
machine:

$ cat tuning
#!/bin/bash

# sudo bash tuning - Ubuntu Studio Quantal

http://wiki.linuxmusicians.com/doku.php?id=system_configuration#pci_bus_...

### Bluetooth
service bluetooth stop

### Network
#service network-manager stop
#service networking stop # does cause serious issues
#modprobe -r r8169 # Ethernet NIC driver

### TerraTec EWX 24/96
modprobe -r snd_ice1712

### Others
modprobe -r firewire-ohci
modprobe -r firewire_core
service cups stop
modprobe -r ppdev # parallel port
modprobe -r lp # printer

### Unbinding devices
echo -n "0000:00:13.2" > /sys/bus/pci/drivers/ohci_hcd/unbind
echo -n "0000:00:13.4" > /sys/bus/pci/drivers/ohci_hcd/unbind

#echo "$ lspci -v " > $l

cat /etc/issue >> $l
