Hmm. I guess we could just try. The fact that you argue that the FP emulation likely hasn't worked for a few years is a pretty powerful argument that nobody has cared. And if somebody does, and ends up having a use case and willing to test, we can always re-animate the zombie that is math emu support. Considering that we don't support the old i386 any more, the only chip I know of that needs it is the i486sx. However, there are probably several clone chips that did the "we're a 486" thing by adding the few integer instructions but not doing a FPU. And there might well be various embedded versions of the 486 that might even be in use still. But afaik most distributions have required Pentium of P6-level capabilities for some time, and I guess any existing old systems aren't going to upgrade their kernels anyway.
