I have not tried to use cramfs with a ramdisk, but I have used cramfs with
the MTD flash layer.  The mkcramfs utility works fine with ARM-Linux.  Two
suggestions:

* upgrade to the latest kernel.  I think cramfs was broke a couple times
during the 2.4.0-test series.
* make sure you set unused portions of the ramdisk to 0xff.  It seems that
unused portions of a partition must be erased for cramfs/jffs to work.

I can confirm this - 2.4.0-test11 had bugs in cramfs - unfortunately
that was the version that I started with when I wanted to make use
of cramfs (which I use via CFI directly from flash).    2.4.1 works
just fine, no modifications.
