Using nm (and cut and grep) to extract names from a
good and bad kernel I find the following, where the
"+" lines are from a bad kernel:

It leaves me wondering if the naming is messing things
up via duplicate naming from the likes of:

static devclass_t generic_pcie_fdt_devclass;

DRIVER_MODULE(pcib, simplebus, generic_pcie_fdt_driver,
    generic_pcie_fdt_devclass, 0, 0);

vs.

static devclass_t bcm_pcib_devclass;
DRIVER_MODULE(pcib, simplebus, bcm_pcib_driver, bcm_pcib_devclass, 0, 0);

(Dual pcib_simplebus based sets of names?)
