I'm booting F21 LXDE successfully on Beagleboard xM rev B. Different DTB but the rest should be the same. Comparing mine to yours you may be loading the kernel at the wrong address. I'm not really using the boot.scr.

Thanks for the reply, Scott. Actually, your post was one of the first ones I saw, and apparently I should have paid more attention to it :-).
Well, I don't think the problem is loading the Linux kernel at the wrong address, but rather using the wrong dtb file. I was using omap3-beagle-xm.dtb, but when I replaced that by omap3-beagle-xm-ab.dtb, at least I got the kernel to boot. I am not really sure the -ab version fully works with rev C, but that's the best I've gotten now, apparently.
the "-ab" just inverts the signal enabling the usb hub.

So running the "-ab" on the "c" just disables the usb hub..
