IIRC, OpenMoko uboot already has support for usb serial emulation (CDC_ACM).
The basic cdc_acm patch came from the handhelds.org SX1 project, and
Harald Welte added
support for s3c2410 USB device controller driver for u-boot
I was able to test CDC ACM on smdk24a0 after making some modifications
to the above patch.
