Stephen,

Can you please post for us peons the proceedure for applying this patch?

I.E.:
Is it only for Linux 2.2.x?
Is it applied to /usr/src/linux/...?
can I use it with 2.0.34 (RH5.1)?
etc.

Some context would be helpful.
 
Reference to a doc/README file discussing any of this would be great.

Thanks!

Maybe someone else could answer these questions if Stephen cannot.

Jont
