We dropped 486 support by accident. It was broken in the kernel by sync_core() using CPUID unconditionally (Debian bug #515982), and then by stack-protector initialisation using RDTSC unconditionally (Debian bug #766105). The latter was reported 5 years after the regression and after it had been included in 2 stable releases, which indicated to me that it wasn't worth fixing.
We dropped 586 support more deliberately, after discussion on debian-devel.
