The changes to the copy_user pipeline code in the latest 2.4.7-ia64
patch break snap 001117 in some circumstances.  There are workarounds
but they require changes to code that is not IA64 related, not
satisfactory.

I have not succeeded building a cross compiler ix86 to ia64 for gcc
3.0, using a current CVS tree.  The flow insn code breaks on some type
conversions in cross compile mode, even when using gcc 3.0 as the base
compiler.  Debugging is still in progress.
