[beagleboard] s-video output stops working when xlde starts

Hi,
Trying to get s-video to work in Ubuntu 12.10 with bbxm.c1.
The setup worked with Angstrom and with a DVI-D monitor with ubuntu.
However, when I change it to s-video output with uEnv.txt and reboot (in
Ubuntu) the screen shows start/boot-up text, but then just before the GIU
loads, it goes black/blank.

cat /proc/cmdline
console=ttyO2,115200n8 console=tty0 vram=12MB omapfb.mode=tv:pal
omapdss.def_disp=tv root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait fixrtc
buddy=none buddy2=none camera=none wl12xx_clk=

my start-up log (http://pastebin.com/TwUyfxAb) and Xorg.0.log
(http://pastebin.com/GaZK6vsL)

Odd, nothing obvious in the logs, anything in xorg.conf? (although
ubuntu might not use that anymore)

Do not bother with this package, it's been un-maintained for awhile,
there is a replacement but we haven't defaulted to omapdrm yet to
utilize the replacement.
