just in case there are any other Murphy victims in our ranks, a quick fix in case the boot inside your Pi gets messed up as mine did today, replace your freebsd sdhc ( or whatever) with a raspbian sdhc card and power up. watch the leds flash, thats your first sign cause it takes a few seconds for anything to appear on an hdmi connected display, but chances are very good it will 'wake up' normally!
 no, I still dont know for sure how I hosed my boot up, but think it was when i copied the command to create a swapfile from the handbook, wrong. 
  hope this helps somebody!
