Having 2 stacks was not really the problem. Since ia64 was the first
"other" platform onto which KSE was ported, extra effort was needed
to remove the inherent i386-isms. Not a biggy, but had to be done
with care. The real problem is in having 2 different ways to enter
the kernel (and leave again). Contexts created when we enter the
kernel through path A cannot be restored while we leave through path
B and vice versa...
