The via c3 boards require that you install and run the i586 kernel (because for some ungodly reason compatability wasn't in via's focus)

No, actually, it's a gcc bug. The C3 doesn't support the CMOV instruction, which is ok according to Intel documentation, and software should check whether this instruction is available. gcc implicitly expects every 686 to have this instruction.

To add up to the confusion, on later VIA CPUs (those with a C5P core and later), you'll actually want to use 686 to initialize the SSE pipeline, which is necessary to make use of the xcrypt instructions (which will otherwise be invalid opcodes).
