This is very cool - looking forward to this hack! 
I'll be glad to test something if you will need more people.

Can't our Linux kernel take care of whole power management and our Dalvik app just let be controlled?

In that case your now looking at patching host kernel to enable Android, which I dare say is going to break a few things a long the way.

If that's the case I'd start looking at a Sailfish approach by running libhybris, if only for the possibility of detaching MCE and co from N900 specifics to allow porting to other devices.

Problem is how much RAM and performance loss your going to see.

If the container has the same kernel, does that mean it has to load two sets of drivers for everything? Or are the android drivers only loaded inside the LXC container?

and why the drivers (the camera one and others ) were patched to work in android(jolla) if they share the same kernel , i don°t think they share the same drivers

by the way why alien dalvik won°t run on kernels prior to 3.x.x (jolla , leaving qualcomm s**t aside) , from what I remember it was demoed on n900 , that phone was with a updated kernel? or our kernel was patched?

Quote from the linked page: "You’ll need a kernel with the Android patches (binder, ashmem, logger etc.)"
[...]
Neither Fremantle will run on Android kernel nor Android will run on Fremantle kernel.
I think that sorta sums it up good enough.
And the same situation in reverse - on my Android device, I can stop Zygote, take control of the framebuffer, and start Xorg with the GNU Userland from a terminal.

Supposed there is static pm missing, what would happen while trying to run an Android app? //edit: Can't our Linux kernel take care of whole power management and our Dalvik app just let be controlled?

I'd say help freemangordon, pali, et al. to run maemo on 3.x kernels, then go from there.
Win-win for everyone.

Well, I was trying to compile LXC and when generating configure by running ./autogen.sh I'm getting:
aclocal: configure.ac: 205: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 219: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 234: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 252: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 269: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 304: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 315: macro `AM_COND_IF' not found in library
aclocal: configure.ac: 377: macro `AM_COND_IF' not found in library
That's probably related to old version of autoconf used in scratchox. Will update & report.
<- solved by downloading .tar.gz tarball & running configure directly.
Another error log, when running make:
In file included from lxc_attach.c:37:
utils.h:56: error: static declaration of 'setns' follows non-static declaration
/usr/include/bits/sched.h:91: error: previous declaration of 'setns' was here
Ideas? <- caused by broken version of libc6 from previous projects. Reinstalling whole scratchbox, will let you know soon
