Actually, the OTG USB is the INTERNAL one used by the 3G modem. The external connector only acts as a device, and does not support host mode. It would be possible to connect the external USB with another USB device such as the USB LCD, but you would need a host bridge device between them.
And you would need special device drivers inside the kindle.
EDIT: I finally found this post again so I could update and correct it. I have since read the freescale manual, which says the internal port is Host-Only, and the external port is OTG (Host or Device mode), so we can connect USB devices to the kindle (like a USB flash drive, or keyboard or mouse). In theory you could connect a USB video display too.
