The Geode isnt an M2 core, and its not licensed. AMD bought Geode outright
from NS. If you look at the timings the Geode is much more a 486 with extra
instructions.
But AMD was is still selling its E86/SCLAN series too (and was its
_only_ product for awhile), which kicks some serious butt at 133MHz,
with lots of on-board peripherials.
Thats 486 with buggy hw emulation.

i486
ISA.
486..
But for plain Jane x86, there is little sense to break i386 ISA
compatibility. Yes, _assume_ the "performance/memory/disk" equivalent
of a Pentium Pro/II or higher. But leave the instruction set
compatibility (ISA) at i386 -- please, for Fedora adoption sake.
Every example you give is 486 or higher ISA, as are the others you
missed that I am aware of - SiS55x for example. Going 386->486 makes a
really big difference.
