Yes, and you weren't using any P-III specific compilation options
before, right?

Either:

1. Don't build P-III optimized code for your P-III,
2. Don't build on your P-III for non-pentium machines,
3. Build on your i486 (much like 2),
4. Mount the i486 root partition on you P-III and
   do the install on your P-III.

Ad 4: it would be nice if we had some sort of staging. That way, the
install can be performed on the P-III. The staging area could then be
mounted by other machines and "installed". This could be as simple as
doing a

	tar cf - ${STAGING_DIR} | (cd /; tar xf -)
