Nope, they are 16 bits still.  When referring to code locations, they
are counted in 16-bit words, however, so with 64 KW of address space,
the entire flash ROM can be addressed.  (All instructions end up on a
word boundary anyway.)

Only .progmem data pointers are restricted to the lower 64 KB of
flash.
