My addled brain has lost track of this.  Was this on FC3?  I just built
ndiswrapper 0.11 on my laptop running FC3 (kernel 2.6.9-1.681_FC3) with
no patches (4K stacks) and it built and runs fine with my Broadcom
BCM4306 using Windows XP drivers.

The trick is, of course, getting the kernel source for FC3.  You must
download the kernel source RPM (there is no "kernel-source" RPM yet, you
must get the SRPM from the SRPM repository).  Install the SRPM via:

	cd /download/directory
	rpm -ivh kernel-2.6.9-1.681_FC3.src.rpm

To make this look like one of the older "kernel-source" RPM installs,
you have to patch the sources and create the kernel source tree.  To do
this, go to /usr/src/redhat/SPECS and run:

	rpmbuild --target i686 -bp kernel-2.6.spec

After some crunching and chewing, the source tree is created...but not
in the spot you expect it to be.  You can move it to the classic spot
by:

	cd /usr/src/redhat/BUILD/kernel-2.6.9
	mv linux-2.6.9 /usr/src/linux-2.6.9-1.681_FC3

Ok, now the source tree is in /usr/src.  Make the appropriate symlinks
in /usr/src:

	cd /usr/src
	rm -f linux linux-2.6
	ln -s linux-2.6.9-1.681_FC3 linux
	ln -s linux-2.6.9-1.681_FC3 linux-2.6

Don't forget to edit "/usr/src/linux/Makefile" to change the
"EXTRAVERSION=" definition to match the actual kernel version.  For
uniprocessors:

	EXTRAVERSION = -1.681_FC3

for SMP:

	EXTRAVERSION = -1.681_FC3.smp

(I think that's it for SMP, "uname -r" will tell you for sure).  Once
you've got that done, you can clean up the cruft left by rpmbuild by:

	cd /usr/src/redhat
	rm -rf BUILD/* RPMS/* SOURCES/* SPECS/* SRPMS/*
	cd /usr/src/linux
	make mrproper

Now you've got the FC3 kernel source just like the old "kernel-source"
RPMs used to make (mmmm!  tasty!).  Copy the config file from /boot to
"/usr/src/linux/.config" and do AT LEAST

	cd /usr/src/linux
	make oldconfig

Once that's done, you've got the kernel source tree configured for your
system.  Assuming you're running that kernel (or you've buggered the
ndiswrapper Makefile to point at this kernel source tree), you can build
ndiswrapper.

As I said, I built ndiswrapper V0.11 in just this manner and it works
fine.  Your mileage may vary.  Void where prohibited.  Batteries not
included.  Etc., etc.
