To get them working for you I have put the files in a zipped pk3 and you can download it here: http://www.intplsrv.net/tltrude/Temp/User-palms.zip .
Of course if you wish to put them in a mod, you'll need to extract the files from my pk3 and move them to yours. I did this by copying the squatpalm lod and sk* files and changing the names for the new palms. Those files are missing in everyones game, until now.
