I knew about the 3600mAh battery but unfortunately I don't possess one, so was not able to add it to the patch. I only have the default 1800mAh battery which shipped with the hx4700.

If anybody here does have an hx4700 with the 3600mAh battery and is able to run Linux on it, it would be a big help if they could apply the following patch to discover the rated capacity register value via dmesg:

--- clean-2.6.39/drivers/power/ds2760_battery.c	2011-05-19 05:06:34.000000000 +0100

 	/* DS2760 reports voltage in units of 4.88mV, but the battery class

Or perhaps HaRET has some means of dumping the register?
