That is true now, but only since ia64 rolled a lot of changes into
2.4.16. Before 2.4.16, ia64 was significantly different, before 2.4.13
ac was a nightmare. IMHO having a core kdb patch with arch specific
add ons will actually make it easier to support multiple architectures,
you don't have to reconcile the core changes from two different patches
because there is now only one copy. By definition, the arch add ons
are completely independent so there are no reconciliation problems.
