Intel were very helpful in getting Linux ported to run natively on the Itanium class of processors. That - and the fact that Linux *is* very portable - helped Linux being the first OS to run on these CPU's.
Itanium/Itanium2 is probably better supported by Linux at this time, and optimizing glibc is mostly a matter of recompiling with your favourite Itanium-specific gcc flags.
