i have modified Generic.kcm and Generic.kl to have my physical keyboard like a azerty and no qwerty.
Don't forget to modified your build.prop if you have a problem. I am not responsable if you brick your tablet S.
Delete ".txt" of the two files
Push "Generic.kcm" to /system/usr/keychars with permissions : Read for all and write for Owner.
Push "Generic.kl" to /system/usr/keylayout with same permissions
Reboot system and it's done
