We sucessfuly use amd64 arch on Intel Xeon CPUs.
EMT64 is fully compatible with the major features in AMD64. However,
IA64 (64-bit architecture made by Intel in older Xeons) isn't compatible
with AMD Opterons AFAIK. Besides, IA64 doesn't allow binary/library
profiling and requires all stuff to be done in 64-bit whereas EMT64 and
AMD64 do allow for 32-bit and 64-bit operation, simultaneously IIRC.

Would U Plz. tell me about MAX amount of RAM freeBSD supports per
processor in SMP systems?
Depends on the architecture. A 32 bit x86 chip can address 4GB, unless
you have the PAE extension in the kernel. In that case it is 64
GB. Beware that some drivers are not compatible with PAE.
As Roland suggested, you should go with non-PAE 32-bit (in this case
64-bit operating system) if you want more than 4GB of RAM. Look up the
archives for this mailing list on recent discussion centered around this
topic.
The amd64 architecture has been tested with 8 GB.
For other architectures, see the release notes:

Does a dualcore system be considered as SMP system? Say an AMD X2 or Core2Duo?
Yes, AFAIK.
Yes, they are. SMP = "Symmetric multiprocessor system", which includes
hyperthreading, multi-processor, and multi-core capable CPUs (or some
hybrid variant of the above).
