Afaik, there are also effecient memory copy/move/fill instructions,
that do not require floating point contex

The soekris boxes have a geode in them, which is a 486. I've run
generic on them w/o disabling SSE for ages...

IIRC, my DX2 486
Does anyone out there have a 486 DX4 even? Can you boot 8.0 CDs?
or not.
If I'm not mistaken this means that the install CDs will no longer
even boot on a lot of machines.

And the crowd roars it's approval!

If I'm not mistaken this means that the install CDs will no longer

If I'm not mistaken, the GENERIC kernels won't boot and run fully on a
real i386/i486 anyway.
