I think Module.symvers generation for external modules was added sometime
around 2.6.16, so its not generated on the older kernels (for eg 2.6.9 kernels
on RHEL)

In this scenario, when there is no Module.symvers file, I guess the other
option is to use a single Kbuild file to build both modules,
as explained in section 7.3 of Documentation/kbuild/modules.txt.

But this may not be feasible always. Come to think of it, why does the
OFED installation procedure not update the kernel Module.symvers file
when it replaces the old kernel modules present in /lib/modules/
with the new ones ?

It might be a good idea to update the Module.symvers file as part of the
normal installation and not only kernel-ib-devel. Because if the kernel
modules are being replaced (or new modules are being added), shouldn't
the Module.symvers file also be updated ?
