[c-nsp] CompactFlash card compatibility

[Scott McGrath]

For a LONG time there was a 512MB limitation on filesystem size i.e. the 
Sup720's would recognize a 512MB CF card but not a 1Gb
card.    Until this thread we were not aware that the limitation had 
been lifted on newer code.   

This is helpful as we have been scouring the universe for old 512Mb CF 
so as not to pay Cisco's outrageous prices for a commodity
product.  esp since you can get a Toshiba 1Gb type I CF card at Sams 
Club for $15.00.
