Thanks for the help, but I am still having problems. I followed the
instructions here:

http://wiki.openmoko.org/wiki/Boot_from_sd_card

to partition, format and populate my SD card with the uImage and rootfs
found here:

http://downloads.openmoko.org/releases/Freerunner/

The phone begins to boot, but fails with a kernel panic. The last lines it
spits out are:

***************************
VFS:cannot open root device "mmcblk0p2" or unknown block(179,2)
please append a correct "root=" boot option; here are the available
partitions:
1f00   2048   mtdblock0 (driver?)

(...)

b300   495488 mmcblk0 driver: mmcblk
  b301 8536   mmcblk0p1
  b302 486864 mmcblk0p1
Kernel panic - not syncing: VFS: unable to mount root fs on
unknown-block(179,2)
***************************

"mmcblk0p2" is the ext3 partition on the SD card with the .jjfs2 file in it.
Does anyone know why the filesystem on my sd card does not mount properly?

(sigh)
