Now I can reproduce the same panic on 3/80 (68030+68882) running
a kernel with options FPU_EMULATE. (GENERIC3X doesn't have it)

Disabling options FPU_EMULATE (or to apply my previous patch)
could workaround it..
(though -m68040/060 binaries won't work anyway)

#include <stdio.h>

main()
{

        printf("executing FDADD..\n");
        __asm(".long 0xf2000466");
        printf("done.\n");
}
