LED white, emitting light sideways. 1.8mm * 1.0mm * ~0.3mm(!) http://maemo.cloud-7.de/share-service/20131223_013.jpg http://maemo.cloud-7.de/share-service/20131223_014.jpg matching component needed. Particularly re height restriction. Alternative(?): use rear-mounted LED shining from other side of PCB through a hole. Problem: change direction of beam 90° to shine sideways into lightspreader of domesheet

RGB 3.0*1.3*0.43mm ~1.00EUR/1; 0.43 height seems in tolerance, 3.0 width TBC http://rohmfs.rohm.com/en/products/databook/datasheet/opto/led/chip_m ulti/msl0201rgb.pdf http://www.digikey.com/product-detail/en/MSL0201RGBW1/MSL0201RGBW1CT- ND/2791603 (not compatible with N900 LED driver concept which only supports 6 LED via LP5523. This however would sum up to 18 LEDs. Needs further consideration, but highly desirable property of changeable kbd BL color.

go for 6* RGB MSL0201RGBW1CT-ND, add 2 pcs lp5523 on same I2C bus (supports 4 distinct I2C addr via 2 ADDR-config pins). Move all kbd LED to the 2 new lp5523, leaving original lp5523 with indicator RGB and 6 open outputs usable to our liking. kbd backlight in fremantle is controlled by mce which recently got RE'd, so sw side is no problem http://www.digikey.com/product-detail/en/MSL0201RGBW1/MSL0201RGBW1CT- ND/2791603 http://www.digikey.de/product-detail/de/LP5523TMX%2FNOPB/LP5523TMX%2F NOPBTR-ND/2270369 (or LP55231 ?)

Unfortunately the LED proposed has a common Anode but we need common Cathode for the LP5523. We can either look for different LEDs. What about http://rohmfs.rohm.com/en/products/databook/datasheet/opto/led/chip_m ulti/msl0101.pdf - but there is no stock at the usual distributors. Or we use a different LED driver (e.g. TCA6507).
