Yes with current versions of Taroon.  I've got a server running with
this now.

This is it.  Alternatively, you can download the qlogic driver from HP
for formal support from HP instead of Red Hat.  Both do the same thing
and work fine.  I've got one system on each right now.  The system with
HP's driver will be upgraded to the Red Hat-supplied one as soon as I
get a change window to reboot with the newest kernel.
