Back uname -a should reveal the architecture the kernel was built for.
another way to check would be getconf WORD_BIT which returns the size of long (32 or 64).
On the app side, i am not sure how to check if you are dealing with a 32 or 64 bit app, of course the rpm itself should have a target architecture referenced in its file name.
