hello,
The Compaq bootldr can do that exactly. Please see:
www.handhelds.org/sources.html ,HOWTO,FAQ ,etc.
The best is the bootldr with JD's patch ,please visit

Good luck!

Subject:Trying to use cramfs image instead of ramdisk as root filesystem...
Date:Wed, 7 Mar 2001 09:18:08 +0800
>Hello,

>I am currently using kernel 2.4.0-rmk2 and a ramdisk on my SA-1110 system.
>This system has 8MB of memory, and I would like to use a cramfs image
>instead of the ramdisk to use the limited memory most efficiently. At this
