G92's seem to require some additional bit of initialization before the BSP engine can work. It feels like clocks are not set up for the underlying VLD engine, which means that all commands submitted to the xtensa chip end up hanging. VP seems to work fine though.
This still allows people to force-enable the bsp engine if they want to play around with it, but makes it harder for the card to hang by default.
