First it does not work because you do not have access to libc in the
kernel.  Secondly your LCD driver is not available at the time of
start_kernel so there is no one to listen to the /dev/lcd.

The quickest hack would be to find your lcd driver and modify it to spit
out the Loading Kernel, after it initializes.
