We are just about to ship 3.2.0 including non-PAE support in SLE10 SP2.
While I'm unsure about version updates for future service packs (this
simply hasn't been decided yet), we'll definitely have to maintain non-PAE
for the life time of SLE10, so a step like this makes our life harder.

Regardless of my comment above, I understand all this, and it is for the
same reason that we decided to drop non-PAE support for future products.
