=== Battery ===
Update; now have a store bought 1500mAh lipo from aliexpress, 2000mAh on the way.
It turns out that a Nokia BP-4L LiPo battery fits perfectly. without any modifications to the case. Uncertain if thermistor matches specs, but it does seem to charge.
As an added advantage, this battery is 1500mAh instead of stock 1250mAh.

Update to battery mod;
Mozzwald made this script ; http://mozzwald.com/zipit/openwrt/chrgstat which showed that the battery wasn't charging at all.
Measuring the thermistor leads from the Nokia battery showed me it had a 119k resistance at roomtemperature, way too high for the charge circuit. I now put just a 9.1K resistor between the thermistor lead and GND, and, its charging \o/

openwrt build

Just to mess around, i went to build openwrt.

Removed all feeds, set these ones;

Needed to do some mods to m4 and bison; (can only do this after failing first) 

build_dir/host/bison-2.4.3/lib/stdio.h
build_dir/host/m4-1.4.16/lib/stdio.h

/*_GL_WARN_ON_USE (gets, “gets is a security hole – use fgets instead”);*/ 
#define gets(a) fgets( a, sizeof(*(a)), stdin)

Also disabled the makeinfo in gcc 

toolchain/gcc/common.mk

MAKEINFO=missing

On alsa-lib i needed to edit package/feeds/zipit/alsa-lib/Makefile to get; 

DEPENDS:=@AUDIO_SUPPORT +librt +libpthread

For ncmpc i need to add some depends aswell; 

+glib2 +libncursesw

Hotplug2 compile needs the mods listed on this site; 

http://stackoverflow.com/questions/25246963/build-error-openwrt-hotplug2

In openwrt's config this needs to be enabled to pull in real iconv; 

CONFIG_BUILD_NLS

Some hints from mozzwald; 

23:28:12 < mozzwald> here's the script I use when doing a full build
