Yes, the IB support is from 2.6.13.1 (kernel drivers at rev 3882). I 
have updated the userland stuff. user_mad.c is currently at the latest

latest drivers?

No, here is what I get with -V:

[surs at ro0:tmp] sudo opensm -V
Password:
OpenSM Rev:openib-1.1.0

Using default guid 0x2c902004002e9

Error from osm_opensm_bind (0x2A)
