I don't think my initrds have been of the cramfs type.

With that config, I can't boot the resulting image because it's too 
large for the silo that I'm using.

[root@sparky linux-2.6.11.10]# ls -l arch/sparc/boot/image
-rwxr-xr-x  1 root root 2921764 May 19 04:34 arch/sparc/boot/image
Built with: gcc version 3.3.4 20040623 (Red Hat 3.3.4-2)

Here's the similar output from the latest Aurora kernel:

Linux version 2.6.11-1.1166sp1 (root@arthur.devel.redhat.com) (gcc 
version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)) #1 Fri Mar 4 21:55:08 EST 2005

No explicit mention of a ramdisk, but nash is the shell used with the 
initrd.

Some more details about that kernel and it's initrd:

[root@sparky boot]# ls -l *1166*

Looks like my initrd is a cpio archive instead of cramfs.

And here's the versions of my mkinitrd and silo:
   mkinitrd-4.1.18-2
   silo-1.4.8-1
