For some reason EA released the game with a f*cked up joypad config file. For me (well for a friend, I've not got it installed on here) it resulted in neither the through ball or the slide tackle controls being set. Going into the game controls section and trying to set them resulted in "empty" being shown instead of the control. To solve it...
Make a backup of your //FIFA_INSTALL_DIRECTORY/data/input/devdata.dat
Then download this file..
http://69.80.255.209/download/19116669a49d5d09/
..and replace the original devdata.dat file over it.
That solved the problem.
edit: @SF.. there is now a keyboard/mouse control option in 09 on the PC..
