The problem is that xetex writes auxiliary files differently than
pdflatex. If the catcode of the tab is 12, xetex writes a tab as ^^I. So
But inside verbatimtab ^ has catcode 12 too, so ^^I is not a tab but
three normal input chars.
It is possible to get a tab by resetting the catcode of ^ to seven:
\beamer at makeinnocent\^^I% and whatever other special cases
But be aware that you no longer can use ^ in other context (e.g. a^b)
inside such a verbatim environment.
