John, now that you also got a Beagle xM rev C, can you check if you're able to reproduce this issue with either Ubuntu's or Linaro's kernel?
Robert, there's a chance that u-boot might also be the culprit, so can you also check using natty's x-loader and u-boot? Just grab both MLO and u-boot.bin from the x-loader and u-boot-linaro packages for omap4 and try to boot your board with them.
