Depends on what you mean by special.  To get any particular baudrate the 
VPB frequency and the baudrate divider have to have a relationship that 
allows the divided rate to be 'close' to 9600*16.  In practice 10MHz works 
just fine.  There will be other frequencies that work well too.  Take a 
look at the user manual.  There is a table of baud rates that can be used 
for ISP with a selection of crystal frequencies that you can use as an 
overview.  If you want to use a particular crystal frequency you have lying 
around you will have to work out whether it's possible or not.
