I think the problem is that the SLES10 kernel already includes Xen
headers (the 3.0.2 version I guess) which are getting mixed up with the
headers supplied in the unmodified drivers tree. The drivers want to
build against their own versions.

Can you run the build with V=1 to check that this is what is happening,
i.e. I expect -I/usr/src/foo is before -Iunmodified/.../include

Can you also have a look
in /usr/src/linux/include/xen/interface/xen-compat.h to see what
__XEN_LATEST_INTERFACE_VERSION__ is.

I'm not sure what the best solution is, as a work around you could try
renaming the include/xen subtree of the kernel source in /usr/src/linux
out of the way.

Ian.
