U-Booting off of the SD card on the Sheevaplug

Finally (2010.09~rc1-2) I am running Debian's U-Boot on the Sheevaplug, and booting with this env:

bootcmd=run bootcmd_mmc; bootm 0x300000 0x0800000
bootargs=console=ttyS0,115200 root=/dev/mmcblk0p2
bootcmd_mmc=mmc init; mmc init; ext2load mmc 0 0x0800000 /uInitrd; ext2load mmc 0 0x300000 /uImage

Having to run mmc init twice is annoying, but it beats dealing with whichever fork I had on it last.
