Its questionable if we should include the 'i'

heh, agreed. let's rename 'em all x86 and be done with it. ;-)

True enough, personally I prefer "x86".

ia32 is the official name. OTOH, i[3-6]86 _are_ different beasts...

IA32 is a retcon, and is used only by Intel anyway.  There are
differences between the i686 lines that are significantly bigger than
between the i486 and i586, and that doesn't even begin to count non-Intel
chips.

However, changing it to "i386" consistently would still work with
existing software.  Using "x86" or "ia32" or "ix86pc" (what Solaris calls
it) would break stuff.

ia32 is an intel trademark. Using it for non intel products is probably an
actionable matter ..

Yet another reason to ignore it.

Speaking of using it for non-Intel products, this is a line from
Documentation/Changes in Linux 2.4.0-test10-pre6:

Linux on IA-32 has recently switched from using as86 to using gas for

Should we change that to x86 or something?

Since Linux generally calls this i386 throughout, I would stick with
calling it i386.
