Win-win for everyone.

I'd also rather see everyone chime together to work on the 3.x kernel, however the reality is that not everyone is a kernel hacker. Their kernel is already quite usable so it should be suitable for initial testing.

I doubt it. Android has been bootable with a vanilla kernel since Linux 3.3.

You can easily find that out by grepping the kernel .config file for each option.

alex@aexbook:~/NeoDroid/maemo-kernel$ fgrep -x -f droid.config .config

^ this, in default make rx51_defconfig generated .config file, just with following N900 specific options enabled:

CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y
CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND=y
CONFIG_PINCTRL_SINGLE=y

Your grep is matching the whole line (-x). Based on your output, I'm assuming that your droid.config file contains entries that only check what is enabled. Options that may be available but aren't enabled by default won't be included.

This is what I get when grepping the 3.x N900 kernel config:

Code:

$ for i in CONFIG_{PM,HAS_EARLYSUSPEND,SUSPEND,HAS_WAKELOCK,WAKELOCK,EARLYSUSPEND,USER_WAKELOCK,FB_EARLYSUSPEND,ASHMEM,ANDROID_PMEM,SWITCH,STAGING,ANDROID,ANDROID_BINDER_IPC,ANDROID_LOGGER,ANDROID_RAM_CONSOLE,USB_GADGET,USB_ANDROID,USB_ANDROID_ACM,USB_ANDROID_ADB,USB_ANDROID_MASS_STORAGE,USB_ANDROID_MTP,POWER_SUPPLY,PDA_POWER}; do grep -E "$i\W" .config > /dev/null && echo +$i || echo -$i; done
+CONFIG_PM
-CONFIG_HAS_EARLYSUSPEND
+CONFIG_SUSPEND
-CONFIG_HAS_WAKELOCK
-CONFIG_WAKELOCK
-CONFIG_EARLYSUSPEND
-CONFIG_USER_WAKELOCK
-CONFIG_FB_EARLYSUSPEND
-CONFIG_ASHMEM
-CONFIG_ANDROID_PMEM
-CONFIG_SWITCH
+CONFIG_STAGING
+CONFIG_ANDROID
-CONFIG_ANDROID_BINDER_IPC
-CONFIG_ANDROID_LOGGER
-CONFIG_ANDROID_RAM_CONSOLE
+CONFIG_USB_GADGET
-CONFIG_USB_ANDROID
-CONFIG_USB_ANDROID_ACM
-CONFIG_USB_ANDROID_ADB
-CONFIG_USB_ANDROID_MASS_STORAGE
-CONFIG_USB_ANDROID_MTP
+CONFIG_POWER_SUPPLY
+CONFIG_PDA_POWER

'+' indicates that the option can be enabled in the kernel.
'-' indicates that the option is not available and would need patching in the kernel. Note that not all of these may be required for running under a chroot/container.

[EDIT]
This list isn't entirely accurate. Some of those options which I have marked as unavailable are actually available but are not present in the default .config file. They get added automatically when you enable a dependent option. Sorry about that.

the purpose is to make the maemo OS to use android aplications , no to make from maemo nitdroid(no calls , gps ,etc etc) ,I was reffering to the mising drivers in the new kernel for n900 (3.x.x), no at general , our kernel(2.6.28) needs to be patched at least until 3.x.x fully support n900(here is the longshoot) , and we know about PM , the next step is to find someone with the skills to patch kernel and after flashing the new kernel , maemo needs to be alive at boot

LXC requires at least linux kernel 3.14 to be secure.
I don't know if someone manage to port specific N900 code to this kernel version, but if not, there is no way to have LXC for maemo.

Any way, to stay on topic, and, as it has certainly already been said above (did not check), a chroot, more over a super chroot such as LXC, is not a solution to run Android, since the point of a chrooted system is to use the host kernel with the user environment of the guest.
And as far as I know, Android kernel features are not integrated in the linux kernel yet.

So, that makes two reasons why LXC won't be a solution for android, at least for now

Yes, pm = power management.

thp used the nitdroid dual boot kernel which has all necessary android modules included
