In linux kernel since version 2.6.29 (release Date: 2009-03-23)
Most LCDs use a single address bit to differentiate line 0 and line 1. Since
some of them need to be able to address 40 chars with the lower bits, they
often use the immediately superior power of 2, which is 64, to address the
next line.
If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and
64 here for a 2x40.
