Sure that is!
Look at pci_msi_set_enable(): it's a single read and then write, just 
like the code for bus master enabling. The msi capability address may be 
retrieved from lspci and then mapped for instance using sysfs.

Configuring the MSI table is a few more reads and writes too but at the 
bottom line - it's a trivial code too...
