I think your drivers should support MSI to be able to use it.
My system has Intel ICH9R and Intel E1000 network, which use the ahci
and e1000e drivers:

[jan at jan ~]$ cat /proc/interrupts  | grep -i MSI
761:     175705     175119   PCI-MSI-edge      eth0
762:     193798     194868   PCI-MSI-edge      ahci

[jan at jan ~]$ dmesg | grep -i MSI
pcieport-driver 0000:00:1c.0: found MSI capability
pcieport-driver 0000:00:1c.1: found MSI capability
pcieport-driver 0000:00:1c.2: found MSI capability
pcieport-driver 0000:00:1c.3: found MSI capability
pcieport-driver 0000:00:1c.4: found MSI capability
