I doubt it's the best way to just add ARCH_X86_64 (and maybe ARCH_IA64). A lot 
of rules files use "ifdef PTXCONF_ARCH_X86". So this has to be reworked to be 
useable in X86_64, as most cases don't make a difference to 32 or 64 Bit.
Maybe it's better, to add a 64Bit entry in the optimization. Thoughts?

Alexander
