Do you just want to look at the code?

If so: the linux kernel source browser is nice starting point.

http://lxr.linux.no

I put ram disk in the search box and one of the first results was the
internal kernel doc file for the ram disk:

http://lxr.linux.no/#linux+v2.6.37/Documentation/blockdev/ramdisk.txt

That file is a little out of date because it talks about rdev, which
was deleted from util-linux last summer I think.  I don't know what
tool / process takes it's place.

If you figure it out, write a patch to the doc file and get your name
memorialized in the kernel git log!

A little more poking around at lxr.linux.no gets you to
http://lxr.linux.no/#linux+v2.6.37/drivers/block/brd.c

Which I think is the source code your looking for.
