Did anyone point you in the direction of the boot-floppy HOWTO?
http://www.tldp.org/HOWTO/Bootdisk-HOWTO/index.html

I played around with this stuff about a year ago. I was trying to make 
a bootable LS-120 with a fully-featured root filesystem. I hadn't been 
using linux for very long, and needless to say, I failed. However from 
what I remember all you need to do us uncompress the filesystem image 
and mount it loopback. Then you can copy in whatever binaries you want. 
Of course it is best if the are stripped. Plus you need to make sure 
any libs they require are also included. There may be a setting in 
there somewhere (a boot parameter?) that tells the kernel how big the 
ramdisk is going to be. Obviously this needs to be reset to the correct 
value.
