[Beowulf] Low cost IB cards

Be sure your OS -- as in "cat /etc/issue" -- has all the bells and 
whistles for IB.  We bought those 4X SDR cards and an 8 port switch 
and tried and tried and tried for over a year off and on and finally 
failed on various flavors of Fedora to bring up OFA/OFED on IB.  We 
finally succeeded with CentOS 5.3 or 4.  Then we brought up CentOS on 
a mixed cluster and now its NFS is failing miserably to communicate 
with some of the older OS's, on which problem you hear more later....

Ugh!

There didn't seem to be any hardware problems, though.
