The smallest possible ramdisk would probably contain just the
/dev/directory with an entry for /dev/console, and a statically
linked application program by the name of /sbin/init or so.

See Documentation/initrd.txt that comes with your Linux kernel
sources.

8 MB is a lot. You can run pretty complex systems there - for
example, the default ramdisk size for the SELF package is 4 MB, about
half of which is unused. See the ELF package as included with our
ELDK, or see ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/ for am
older (and smaller) version.
