Note:
You may or may not need to update your initramfs, you should if
any of the modules installed are part of your initramfs. To add
support for your distribution to do this automatically send a
patch against "update-initramfs.sh". If your distribution does not
require this send a patch with the '/usr/bin/lsb_release -i -s'
("Ubuntu") tag for your distribution to avoid this warning.

Your backported driver modules should be installed now.
Reboot.

Action: to understand what the scripts in backports/scripts do.

Use the command to build:
quilt push -a;fdr clean;fdr binary;quilt pop -a

There's a .blacklist.map in backport/ :

# Update this map when a driver gets renamed or
# symbols from old drivers get moved to a newer
# driver. If you have the driver on the right
# hand side it will be blacklisted upon installation
# only if you actually installed the driver on the
# left.

# new-driver old-driver

This file is used by backport/scripts/blacklist.sh, it's simply a map used to blacklist old module name to new name. I think this file is necessary for postinst.
