I'm afraid this is more of a report, as I've poked around, but
solving the apparent order-of-operations problem requires knowledge I
lack.

I started with 

FreeBSD g1-37.catwhisker.org 8.0-CURRENT FreeBSD 8.0-CURRENT #745: Sun Apr 13 08:43:32 PDT 2008     root at g1-37.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY  i386

fetched the patch & applied it (without apparent issue -- patch(1)
reported success for each patch, certainly).

The "make buildworld" proceeded without incident, but "make kernel"
died during "make depend" in "firmware":

>>> World build completed on Sun Apr 13 20:03:34 PDT 2008
...
>>> Kernel build for CANARY started on Sun Apr 13 20:03:34 PDT 2008
...
>>> stage 3.1: making dependencies
...

g1-37(8.0-C)[15] 


Checking for files of similar name:

g1-37(8.0-C)[16] find . -type f -name vnode_if.\*
./sys/kern/vnode_if.src
./sys/tools/vnode_if.awk
g1-37(8.0-C)[17] 

So it *looks* to me as if sys/tools/vnode_if.awk might have needed to be
fed to awk(1), eating sys/kern/vnode_if.src & creating vnode_if.{c,h},
perhaps, but that apparently needs to happen before "make depend" is run?

I'm willing to experiment (as I'm able).

Peace,
david

I submit that "conspiracy" would be an appropriate collective noun for cats.
