Yes, it's there.  Here's the DTS entry in case anything else sticks out:

		usb at 23000 {
			compatible = "fsl-usb2-dr";
			reg = <0x23000 0x1000>;
			#address-cells = <1>;
			#size-cells = <0>;
			interrupt-parent = <&ipic>;
			interrupts = <38 0x8>;
			phy_type = "utmi_wide";
			dr_mode = "peripheral";
			sleep = <&pmc 0x00300000>;
		};

I think dr_mode was required in past kernel versions as well (since I
seem to recall bumping in to the problem you describe a long time ago
when we first tried to get device-mode USB working).  :)

Thanks
