On reading the Polish forums forum.ubuntu.pl there is a sticky explaining how to edit the xorg.conf file as above to get Polish keyboard.
One poster: "I can have a keyboard in any language I want except Polish"
Another: "Polish letters worked fine in Dapper but in later versions I not not have all the characters in the usual places"
These seem to refer to Edgy, but the problem is also in Feisty
