I'm 99% sure uname -a will only show you the currently installed OS setup. I am on the understanding that if you have 64bit hardware, but 32bit OS installed, then it'll show up as 32bit.
what you could do is run:
cat /proc/cpuinfo | grep "model name"

then do a search for if this cpu is 64bit compliant. for example, i have the intel E6550 as my BE hardware processor, so going to ark.intel.com shows that my 'instruction set' is 64-bit. http://ark.intel.com/products/30783/Intel-Core2-Duo-Processor-E6550-4M-Cache-2_33-GHz-1333-MHz-FSB?q=e6550
