Sure. You know when the device was reboot. You know the counter values at that time. You don't know what happened just before the reboot. So: at boottime-1: enter U (unknown) into the RRD at boottime: enter 0 (zero) into the RRD at <now>: process as usual. The boottime is known, or can be calculated from "now" - "uptime".
