Volume up and power does make a data reset - (doesn't deploy the original image though). While it is doing this reset, it says that the update is completed - maybe it /is/ the recovery (just modified - I'd totally agree with Kobo devs that nobody ever goes into the stock recovery to do anything - because it's useless).
Btw, the device's platform per se (imx51) is very well documented over at Freescale, although you have to make an account. They have lots of stuff there - images for Ubuntu and Chrome OS for example :-)
