If I understand this correctly the 'letterpaper' option sets two special
macros which are not passed to xelatex (or pdflatex) engine (in sense they
don't know what this macros should do). The information about paper size
is inserted into document in apropriate form by geometry
package (with the help of \special command).

I post another example but with wrong option :(
