Hi,
Will try to answer as much as I know (hopefully it is correct info as well)

Intel Atom is part of the x86 (also called i386 and its successors -
i486/i586/i686) and x86-64 (also called amd64) families.
AMD's processors also fall into the same category.
http://en.wikipedia.org/wiki/X86-64

Since the 64-bit ( x86-64/amd64) processors are backward compatible, 32-bit
kernel and user land can be used on these as well.

"Intel Atom is the brand name for a line of ultra-low-voltage x86 and x86-64
CPUs (or microprocessors) from Intel, designed in 45 nm CMOS and used mainly
in netbooks, nettops, and Mobile Internet devices (MIDs)"
http://en.wikipedia.org/wiki/Intel_Atom

Hope that clarifies that part.

lpia has been dropped since 10.04 Lucid

The announcement of that decision is here  :

The Atom processors are part of the same larger x86 and x86-64 arch, so its
not a significant problem.

Hope that helped.


Thanks,
