You are making it too difficult. I can't think of any 64-bit capable cpus that are not 64-bit capable. Really! :-) The normal question is how can you tell from a 32-bit system, such as a live cd boot or some such, whether the system is 64-bit capable? The answer to that question is to look at the cpu flags and see if the "lm" flag is present. That is the long-mode flag and if present indicates that the cpu is 64-bit capable. $ grep --color '\<lm\>' /proc/cpuinfo If that flag is present then you are good to go for a 64-bit system.
Well, probably the simplest ("newbie") method would be to download both versions (i386 and amd64) of Debian. Then, pop in the 64-bit CD.
1) If it runs, you own a 64-bit system.2) If it doesn't, it will explicitly inform you about the wrong architecture. Use the 32-bit CD and enjoy!
P.S. For anyone owning more than a single computer and/or maintaining computers for various relatives & friends having both versions of Debian CDs handy is a must anyway.
