Take a look at Mandrake's /etc/X11/XF86Config and see which devices it sets
up for your mouse and keyboard. Then, do a 'ls -l' on the mentioned devices,
so you see the real location (instead of the symlinks), and use these
devices on your LFS XF86Config.
I'm not sure, but I'm guessing /dev/psmouse for your mouse and /dev/psaux
for your keyboard.. But please try the above for sure.
