I just looked at my Xen hg tree checkout, and I see that Xen builds IB
drivers for its kernel too.  Does the Ubuntu Xen kernel really turn
off the IB modules?

Hmm, no it does include them.  I just checked:

$ dpkg -L xen-image-xen0-2.6.16-11.2-generic|grep infiniband
/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband
/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband/core

/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband/ulp/srp/ib_srp.ko

So I would recommend just using what Ubuntu packaged for you, no need
to mess around with the OFED kernel module build.

BTW, any reason not to use Ubuntu's 2.6.17 Xen kernel?  I honestly
don't know much about Ubuntu's Xen support so maybe the 2.6.16 kernel
really is better.
