bcmwl-kernel-source fails to compile for 2.6.35 (works with 2.6.32)

Like bug #584180 only build essential and dkms-dev are installed

Note error: this usually happens when the kernel header files are not installed - typical newbie mistake that I did not make.

$ uname -r
2.6.35-25-generic-pae

Hmmmm....
simon@envoy:/usr/src/bcmwl-5.60.48.36+bdcom$ locate "autoconf.h" | grep "2.6.35"
/usr/src/linux-headers-2.6.35-25-generic-pae/include/generated/autoconf.h

Do I read this right: the build is looking for autoconf.h as

/usr/src/linux-headers-2.6.35-25-generic-pae/linux/autoconf.h

I don't see what is trying to look there so I can change it.
Note: this breaks the wireless for all installed kernels.
