On my onboard SunBlade1500 5703 chips, which lack firmware, the APE changes introduce bus timeouts while bringing the chip up, specifically I get crashes in tg3_write_sig_post_reset() such as:

My initial suspicion is that TG3_FLG3_ENABLE_APE isn't being set right on these firmware-less cards, or some APE programming is not being guarded properly with tests on that feature bit.
