IA32 is "regular" x86 (from 386 up to Athlon XP and Pentium 4)
IA64 is what Intel's Itanium uses ("EPIC")
AMD64 is "x86-64", AMDs extension to IA32 the Athlon 64 and Opterons are using

I wonder when "IA32e" software pops up as there actually seem to be some slight differences between intel's and AMDs 64bit extension to the x86 ISA...but i don't know if that will actually require different drivers i
or something...
