Not much I fear:

If someone is interested I can give same results for 64bit Xeon system,
but that's powered off right now.
However, I just ran lshw and that gives me:
product: Dual-Core AMD Opteron(tm) Processor 2218
vendor: Advanced Micro Devices [AMD]
physical id: 4
bus info: cpu@0
version: Dual-Core AMD Opteron(tm) Processor 2218
serial: To Be Filled By O.E.M.
slot: CPU 1

capacity: 2600MHz
width: 64 bits
clock: 200MHz
capabilities: fpu fpu_exception wp vme de pse tsc msr pae mce

_opt rdtscp x86-64 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm cr8_legacy
Please have a look at capabilities, where x86-64 is mentioned. Thus
right now I would suggest using lshw|grep x86-64.
Sorry, that I don't know where it pulls this particular info from.
