Just to be clear here, you what to run the os from the external SDcard
slot? or install from the SDcard slot to the internal storage? Have you
looked at olpc-os-builder to create an image with your rpms

To install to an external SDcard for 1.5, 1.75, 4's you would need to
have your *.zd file on a usb flashdrive inserted into the XO, access
OFW's OK prompt then type:

devalias fsdisk ext:0 <enter>
fs-update u:\<image>.zd <enter>

<enter> is the enter key
replace <image> with the name of the image you want to install.
Please remember that *1.zd is for XO-1.5's, *2.zd is for XO-1.75's,
*4.zd is for XO-4's.
