Greg,

This is an interesting question. Many embedded linux systems
use initrd as the permanent root file system loaded from flash.
What you are proposing should be possible, since relatively 
speaking you have gobs of memory to work with. Check 
out this big blue document on the topic

http://www.ibm.com/developerworks/linux/library/l-initrd.html

This useful too:
http://www.faqs.org/docs/evms/x3834.html

You'd need a large ramdisk to fit all that in there, but in 
theory at least it seems feasible. There is kernel parameter
initrd= where you can specify memory address and the 
ramdisk size, for example

initrd=0xa1500000,8M root=/dev/ram
