[SOLVED] LiveCD not recognizing MMC

[something_about_penguins]

I'm trying to install Gentoo on a Lenovo N21 Chromebook, but, for whatever reason, the livecd environment (minimal install) can't find the MMC on which I want to install the thing. The command ls /dev on the distro I already have installed shows mmcblk0 like it should, but when booting from the livecd does not. fdisk and parted can't detect it either, and it's not in /etc/fstab.
Is there anything that I can do to partition the MMC, or will I have to try using the system rescue CD? Any help would be much appreciated.
