Hi,

Tried to build and and install b2g using dual boot, but at the end just see 
black screen with "mozilla" on the right bottom corner. Also volume button 
shows line at the top and "long power" shows full screen menu (airplane 
mode/silence/restart/power off). Look like I am missing something very small 
and last thing :)

Would love to test it on my device, please help if anyone interested.

What I did:
1. Got Siyah (NoSwap) and Semi v18 ROM for primary boot (post 
http://forum.xda-developers.com/showthread.php?t=1650948)
2. Prepared environment for Ubuntu 12.10 x64: gcc 4.6, linked 
libX11.so/libGL.so 
(https://developer.mozilla.org/en-US/docs/Mozilla/Boot_to_Gecko/Firefox_OS_build_prerequisites?redirectlocale=en-US&redirectslug=Mozilla%2FBoot_to_Gecko%2FB2G_build_prerequisites)
3. ./config.sh galaxy-s2
4. Added firmware in supported list:
[b2g]/device/samsung/galaxys2/extract-files.sh
"Semi v18 UCLE5 Base")
  FIRMWARE=UCLE5 ;; 
5. built, flashed and installed gaia 
(https://developer.mozilla.org/en-US/docs/Mozilla/Boot_to_Gecko/Dual_boot_of_B2G_and_Android_on_SGS2)

Some suspicious logs:
