Note there are no backports for 2.6.27-rc1.  I think this is 
makefile/bldenv issue.  I'm willing to debug this.

Also, i'm going to be taking Tom Tucker's fast-reg patches and adding 
them to ofed-1.4#ofed_2_6_27.  I'll try and get all this working on 
2.6.27-rc1.  How does that sound?

Also, did you include the nfsutils package in ofed-1.4?  We'll need that 
for mount.nfs.

Thanks!

Steve.
