Yes, I can boot the system with initrd, and mount the cramfs and access all
the files. I also did use -r option to build the filesystem image.
I do not have proc built inside the kernel and no /proc directory. I do not
have any /var and /tmp directories in the cramfs. How do I mount /var or
/tmp inside the ram?
What else should I check? I have 2.4.18 stock kernel. Am I supposed to apply
any patch for cramfs to work?

Are you sure? Can you mount the same filesystem when running with
root filesystem mounted over NFS or from a ramdisk?
Did you remember that you might need the "-r" option (reverse
endian-ness of filesystem) when creating the filesystem?
