Sure we really care about them being included on amd64 images?
amd64 machines are powerful enough to the increase of memory
due those module be mostly ignored and about ia64 I do believe
we'll end up supporting them once kernel does it properly.
I see i386 case mostly a workaround due our backward compatibility
for older machines. I do agree that this is really important, so
makes sense to provde a specific image for xen. This isn't the case
for amd64 it doesn't makes sense for me.
Only con I see about having it in all amd64 images is that we'll
need to be carefully how to proper document it. Besides that, I
see no problem with that.
