Luckily, I'm working on a kernel compile right now, so I was able to take a quick look in the scsi config section. There seem to be 3 modules that might support your card. Their names are
qlogicfc
qla1280
qlogicfas
I can't tell from the description which module, if any, will actually control your card. I think the first one is the most likely though
A quick
Google search shows that people have been successfully using that card for raid control for years now, so I expect that you should be able to get it working without too much trouble.
