Hi Anthony,
Thanks for you reply!I didn't enable OFED because I saw this in the README of Mallenox's driver:
2.2 Installing the Driver-------------------------------------------------------------------------------  |----------------------------------------------------------------------|  |Note: Prior to installing the driver, please re-compile (and install) |  |      the kernel with NO OFED options/devices enabled.                |  |----------------------------------------------------------------------|  

 Best Regards,

 The kernel needs to be compiled with OFED to use the IB core modules.

Check out the instructions on the wiki and let us know what worked:

Cheers!
