According to https://wiki.debian.org/ArchitectureSpecificsMemo#i386-1
[ FWIW, it was difficult to find that page, because the natural search
  terms like "baseline" are missing.  ]:

    - i686 since Debian 12 'bookworm'. There's no MMX nor SSE.
    - Before that, "almost" i686 (no "long NOP"/NOPL) since Debian 9 'stretch' (gcc-6 6.1.1-1).
    - Before that, i586 since gcc-4.9 4.9-20140411-1 (2014).
    - Before that, i486 since gcc-4.1 4.1ds7-0exp7 (2006).
    - Before that, i386.

Whereas my processor is a Pentium-III (mobile), i.e. an evolution of the
Pentium-II itself an evolution of the famous Pentium Pro (aka *the*
original i686).  It has SSE but not SSE2 which only came a bit later.

[ The vast majority of CPUs after i686 are already supported via amd64,
  so I don't understand what would be the benefit of raising the baseline
  even further.  ]

Will do as soon as I'm back in the office where I have access to
that laptop.
