[ubuntu] Compilation of old RAID*drivers ??

Hi

I switched my MacPro early 2008 from OSX to Ubuntu with a lot of success. I have one issue with my Raid Card in the MacPro. It's a Caldigit one and manufacturer supplies source files to compile driver on Linux but they are pretty old and don't compile on current Linux versions :( Drivers are avalaible on this link: http://www.caldigit.com/support/CalDigit2.0.2.zip
Any idaes what to change in the Makefile to succeed to compile it ? as I'm definitively not a programmer :(

Thanks
