I got e17 to run in X full screen direct on framebuffer device on a cheap android tablet.

The tablet was rooted and ROM updated with a cyanogenmod to android 4.0 (i think).
Via F-Droid Lil' Debi was installed, and then a debian stable was bootstrapped.
In chroot needed packages was installed via apt: enlightenment, xorg fbde driver, mouse driver, keyboard driver, multitouch driver.
Some device nodes has been added in chroot's /dev , mainly /dev/tty0..4, /dev/graphics/fb0..4 (even if only fb0 is used, I need to discovery what other fb devs are..), input/event0..8 input/mouse0 input/mice

As evdev don't work in this setup, every input must be configured in /etc/X11/xorg.conf. ATM I can't get touchscreen to work, so I'm testing it using tablet cover's usb keyboard and an usb mouse.
USB mouse is mapped to /dev/input/mouse0, but keyboard can change it's /dev/input/eventN device. I'm updating it manually, I think I will write a small script which parses /proc/bus/input/devices and setup keyboard device in xorg.conf.

Last step is to stop Android UI to leave framebuffer device to te full control of Xorg.
Thanks to google I've found which process to stop and restart, and everything works (almost)!

Now I have a script that stops android ui, enters chroot, starts Xorg and enlightenment, and when e17 exits, stops Xorg, exits chroot and restarts android ui.

The icing on the cake would be to have the touchscreen to work under Xorg...
