It's not 0xF000FA6E, it's F000:FA6E, i.e. segment=0xF000, offset=0xFA6E.  
So the way to pass this address to farptr functions is like so:

	_farnspeekb(0xFFA6E);

that is, (segment << 4) + offset.

This is all explained in the library docs, btw.  If the docs somehow 
doesn't make this clear, please say exactly what is unclear there.
