Any filesystem which works with a normal block device, such as a hard
drive, will work with a ramdisk. Read ramdisk.txt and initrd.txt in the
linux/Documentation directory, in your Linux kernel source tree.
cramfs is nice but still read-only at the moment... You might be able
to get away with stacking ramfs on top of that. If not, it shouldn't be
hard to modify cramfs so that it allows fs modifications... just stick
the updated pages in RAM until the file is unlinked or the fs is
unmounted.
