I've been working (separately) on porting OpenAFS 1.2.11 to Linux 2.6
for some time now - I have it using the kbuild infrastructure, which
will produce the .ko files as expected by the 2.6 Kernel.

My port is quite a bit different than that seen in 1.3.64; It's quite a
bit more invasive, as I've chosen to allow the kernel to use its own
heuristics for cache management. This means that it uses the in kernel
inode cache rather than OpenAFS's internal cache.

My patches are by no means complete, but they're getting pretty close.

I've posted them here:
ftp://ftp.suse.com/pub/people/jeffm/openafs/linux26/openafs-1.2.11-linux26.diff

Perhaps you can use the Makefile infrastructure used in them. Note that
the Linux kernel makefiles are a lot more picky than the stock openafs
Makefiles. A good deal of my patch was just to get it building.
