[O] Different set of packages for LaTeX export

[Manfred Lotz]

Hi all,
I have configured LaTeX export for using xelatex. For this I have
defined a list of packages in org-latex-default-packages-alist. One of
those packages is hyperref with certain options.

When creating a normal document, e.g. using class article that works
fine.

When creating slides, i.e using beamer I get an option clash
during compiling the tex file because beamer did already load hyperref.

How can I solve it? 

Could I have a different package list if the class is beamer?
