Look at options(4) for MEMORY_DISK_IS_ROOT:

     options MEMORY_DISK_IS_ROOT
     Forces the md(4) RAM disk to be the root device.  This can only be over-
     ridden when the kernel is booted in the 'ask-for-root' mode.

Leaving out that option should allow you to then use your CF as the root
device.

Also, do you really want to leave the memory disk in if you are using CF
on root?  I'd guess that you probably don't want any of the memory disk
options.  That's just burning a chunk of RAM otherwise...
