I am trying to build a small initrd, with a linuxrc that does something.
Does somebody have such a ramdisk.image available?
Or even some suggestions on what to do?

I started off by trying to make bash my /linuxrc. Bash
required ld.so.1, which required libc.so.2, etc....

This occupied more the 4MB. At that point the /dev/ram on the
machine I was building the ramdisk started giving problems -
If I built a bigger /dev/ram, after umount, dd would only
read the first 4MB.  is there something magical about 4M for ramdisks?

Yes. If you want more than 4M, let's say 8M, you have to boot with a
kernel argument ramdisk_size=8192. If you have kernel sources installed,
you can read about this in /usr/src/linux/Documentation/ramdisk.txt.
