incredibly pedantic note here and not sure why i never noticed this
before but i downloaded the current shipping BB-xM image as linked to
from here:
http://elinux.org/Beagleboard:BeagleBoard-xM
created my micro SD card, my xM booted just fine, but when i went to
display the kernel command line that had been used, this is what i
saw:
# cat /proc/cmdline
omapdss.def_disp=dvi root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait
