Can't access eMMC when using LTIB rootfs with newer (3.11.4) kernel, why?

I'm using mainline kernel 3.11.4 with SABRESDB and the LTIB-supplied rootfs, and just noticed that I can't see the eMMC.

If I insert the SD card, then "cat /proc/partitions" shows me:


major minor  #blocks  name

179        0    7761920 mmcblk0

179        1    7753728 mmcblk0p1


But with it removed, there's nothing listed (even though eMMC is there).

If I switch back to using the LTIB-based kernel, eMMC shows up in /proc/partitions.

What is it in the kernel that I need to tweak to see eMMC?
