SDIO power work-around for B2

I would like to wire up GPIO2, otherwise known as MSDT, to control
power to SDIO slot #2 (WLAN) after an ECO. The ECO will be one
trace cut and one blue wire.
I don't know where in the plumbing this should happen (a quirk in the SD
stack, allowing it's reuse in B3 ?) but I believe OFW will have to
the configuration of GPIO2/GPIO3 as well.
I'll provide units wired this way tmw. for testing.
