Is it possible you installed the base system (make installworld), without 
having installed the kernel (make installkernel)?
If that's the case, without an external drive or backups, your options to get 
a working system again are very very slim.
The only two things I can think of that would work, is an usb memory card with 
the 6.x mount command on it, that you'd run to remount / rw and take it from 
there. Or a bootable memory card with 7.x kernel.

However, it would help a lot if you could give a bit more information:
- how does the kernel identify your disk (drive letters and numbers)?
- Can you capture anything like a verbose boot or dmesg?
- Output of `mount -a -d -v' command
- How you determined your upgrade went wrong and you "run 6.x".


Problem with today's modular software: they start with the modules
    and never get to the software part.
