As a by-the-by, does anyone know a way of determining the linux kernel version used? I can't seem to find anything in the firmware itself (short of reverse engineering) and all I can find in the user partition is a text file named "version" in .kobo containing "2.6.35.3" which is indicative though not definitive of course.
Now if 2.6.35 is the kernel version used, then this may help explain the high power consumption (though not the trigger for the problem itself) since there was a bad power regression of around 18% over previous kernel versions introduced in 2.6.35 and a further cumulative regression of 5% introduced with 2.6.38 according to Phoronix. Other sources will no doubt confirm this.
