The ath9k in 2.6.27-rc5 is working famously for me on my Thinkpad T60 AR5418. I'm even creeping past 11g speeds (25MB/s on a good day). Here are instructions for compiling the kernel in Debian: http://www.thinkwiki.org/wiki/How_to_install_the_development_version_of_atk9k. There is also someone on Ubuntu forums who has created a script to compile the module for pre 2.6.27 kernels and stick it in a .deb package for you. I have found this be compatible with Debian, though I haven't tried out his latest version http://ubuntuforums.org/showpost.php?p=5535562&postcount=3.
I used to use madwifi and didn't experience the kind of problems you speak of. I did however notice that somewhere along the way, there was a regression that slowed down the connection by a non negligible amount http://madwifi.org/ticket/2043. You might try downloading 3401 snapshot (I think you use the "-r 3401" as an argument to svn). I had meant to pinpoint exactly when and where this regression occured, but then ath9k came out and there was an exponential decay in my caring coefficient.
