I send this as a private mail to you.
First thanks for opening a possible door to the SWAP stuff.
I don't full understand your rotting problem.
With recent binutils (see 
http://sources.redhat.com/ml/binutils/2004-07/msg00110.html) everybody on 
ia64 hardware can build big-endian images on a little-endian linux machine. 
Only some special make flags in mini-os/arch/ia64/arch.mk (and the SWAPs) are 
needed to build a big-endian mini-os on ia64-linux. So a running big-endian 
mini-os on xen-ia64 is already a regression test itself I think.
So the most currently used interfaces are checked with a running mini-os. 
Maybe for some more interface regression tests are possible/needed.
What do you think? Where is my mistake in thinking about this?
Thanks.
Dietmar
