It should work if one Neo is set to Host mode and the other one set to Device mode. One Neo could give power to the USB-port it the other Neo's battery is low. (I have to verify this)

echo "host" > /sys/devices/platform/s3c2410-ohci/usb_mode echo "1" > /sys/devices/platform/neo1973-pm-host.0/hostmode
This'll put the Freerunner in to powered USB host mode, then just plug in the keyboard and it'll work. Personally I've made a .desktop file to switch into and out of host mode. To switch back to unpowered device mode just run:
echo "device" > /sys/devices/platform/s3c2410-ohci/usb_mode echo "0" > /sys/devices/platform/neo1973-pm-host.0/hostmode
