   Yes Vince,  I've run in on both x86 and x86_64 - works the same on either.   
      
   I've always used Gentoo as my base OS compiling MBSE by hand.

   You shouldn't,  the Linux kernel has pretty much 100% coverage from the    
   32bit to 64bit drivers - I have heard of a very select few odd-ball    
   devices that are no supported in 64bit.

   All those apps should do just fine, if not better for the database    
   engines, under 64bit - you will need a bit more memory as 64bit apps    
   will be aligned to 64bit (vs 32 bit, which just means the smallest    
   programs grow by a small amount) - but the tradeoff is the the OS can    
   address a WHOLE lot more memory as compared to 32bit.   
      
   DB2 servers at the 'office' have been known to have 512G (as in 1/2 a    
   terrabyte) of RAM with 80% of the memory assigned as shared for the    
   database engine.   
      
   Good luck with the transition,  a bit of advice - rebuild, don't try to    
   'upgrade'.
