These things usually sit off a serial port.
I.E. /dev/lcd is a link to /dev/ttyS0 or whatever.
Anyway the main point is you don't have access to libc.
So how can you access the serial port from the booting
kernel. Well to spit kernel messages out the serial
port you pass the console=ttyS1,19200

The CF should be logically treated as an IDE harddisk. So the fix is
probably have a kernel parameter that causes the following check to
