And indeed, after doing all the mmc-pwrseq and vmmc-supply magic, I now get a response from the SDIO card: (manufacturer 0x2d0, product 0x4330)at sdmmc0 function 1 not configured (manufacturer 0x2d0, product 0x4330)at sdmmc0 function 2 not configured which indicates that we're dealing with a BCM4330 (or at least one of its family members) here.
