tar -Scvzf "$name-$vrev-source-only.dkms.tar.gz" \
   dkms_source_tree/ dkms_main_tree/

# the 'madwifi-0.9.4+${revno}-source-only.dkms.tar.gz' should be
# able to be taken elsewhere

## Now, load it to dkms
sudo dkms ldtarball --archive=$name-$vrev-source-only.dkms.tar.gz

## Now, you can build a debian source package
### read /usr/share/doc/dkms/HOWTO.Debian for more info
sudo dkms mkdsc -m madwifi -v $vrev

## see LP: #928007, you need kver=$(uname -r)
sudo dkms remove $name/$vrev -k $kver
sudo dkms build $name -v $vrev -k $kver

sudo dkms install $name -v $vrev -k $kver

# edit /etc/modprobe.d/blacklist-ath_pci.conf to have:
blacklist ath5k

sudo rmmod ath_pci ath5k
sudo modprobe ath_pci

## maybe a bug in dkms
## after a new kernel upgrade, wifi wasn't present.
## I had to:
for act in remove build install; do
  sudo dkms $act  madwifi/0.9.4+$revno -k $(uname -r)
done

-----
Bug covering bad ath5k performance in karmic is at [1].

Combined instructions on getting functional driver at [2] with [3] to build
dkms.  Added script madwifi-ath-speed-down to lower rate on ifup to
/etc/NetworkManager/dispatcher.d .

I *did* do a 'make install-tools' to put files in /usr/local/bin

switched blacklist from ath_pci to ath5k in
/etc/modprobe.d/blacklist-ath_pci.conf
