Instead of copying a whole subdirectory from a later kernel (which
will likely not work), you can try to apply only the patch you need to
the current version of the kernel.

Yes, I knew this was unlikely to work.

There are instructions on how to build a custom kernel based on the
CentOS kernel but with additional patches here:
http://wiki.centos.org/HowTos/Custom_Kernel

I am familiar with this page and also the very helpful
<http://wiki.centos.org/HowTos/BuildingKernelModules> :)

I believe this is the patch you want to apply, right?

Yes, I've been through this thread a couple of times. There
are several patches actually applied in the course of this thread.
I'll go through it again and try to apply the same patches in the
same order. And there are a couple other patches that show up
later in the year fixing other things related to hdlc/wan. Do you know
of a clever way to scan through the change logs for the relevant
entries?

If so, the comments on the original post on that thread suggests it
works on kernels up to 2.6.22, that might end up including 2.6.18 as
well, so you might have luck with that...

Yes, thank you for your reply. I'll take a whack at it.
