How wonderful!!
I would never have hoped in such a reply, you even gave me the scripts 
to compile OFED under Ubuntu automatically!!
THANKS A LOT !!!

Only one more question: did I understand correctly that you suggest me 
to use the in-kernel modules on Ubuntu or vanilla kernels, even if I 
compiled OFED for userspace?
Otherwise, how should load those from OFED? I think modprobe does not 
find them unless they are in /lib/modules/mykernel, and your script does 
not put them there, it seems to me.

Thanks again!
