#2To think that support for something so edge-case has been supported this long is remarkable.
Even very basic embedded x86 processors are 80486 caliber. Those more feeble than that have no hope of running the current kernel in any meaningful fashion.

#3The 386sx was a fun processor. Lack of a math coprocessor was fun to work around. I'm surprised support lasted this long.

#5I would have thought that support for this architecture would have been useful to keep, since a lot of rad-hardened systems (think space, satellite applications) still use it.

#6Wait you mean it won't run Linux now even if I press the turbo button?

A rad hardened machine won't be running 3.7, or 3.6.x for that matter. They will be running something a bit older with (guess I don't know for sure) security patches being back ported as needed.

Applications that use those sorts of chips probably also use really old versions of the kernel (if they use the Linux kernel at all), versions that they validated for their use case many years ago and then never updated.

Apparently Intel has had a Radiation Hardened Pentium for 14 years:

Those satellites that are going up with the old radiation hardened 386 are going to have to run a version of the linux kernel 3.7 or earlier. I suspect they are conservative with regards to their kernel choice anyways, so that should be okay.
