git pull will happily merge into a non-HEAD checkout. If you do something
like this (inside your linux-2.6 checkout):

git reset --hard v2.6.26
git pull git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git
git pull git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/my-wireless-testing.git ath9k

Then you get a minimal, incremental set of changes based on 2.6.26 (which is
what most wireless-testing users will want). There are some drawbacks but it
sure beats wasting several hundred megs on two git repos.

If you want to go back to Linus you just do:

git reset --hard v2.6.26

And it'll blow away all the merges (since you were never tracking those trees).
