After my try with the MIIX300 failed but since I am still desperately looking for a really small but rather powerful subnotebook I finally gave in and ordered a refurbished Thinkpad Tablet 10 (TPT10). With the Ultrabook Keyboard it could turn out to be a very versatile, pretty powerful, low power mini laptop for travel and work. It comes with Windows 8.1 Pro 64 preinstalled which I of course need to get rid off. I hope this will work out better than on the MIIX300. I am pretty confident since the TPT10 was marketed as a higher end business machine so I hope that the components built into it are not of the cheapest and thus least supported nature.
According to the EAN number my model will be pretty well equipped, it should be model no. 20C10024GE which contains:

*1 Even with kernel 4.5.2 I sometimes get the Baytrail typical mmc timeouts 🙁 This could be a fix!?
Update: Yes, this is the fix, which has been upstreamed in 4.5.3 and 4.6
*2 ACPI DSDT table has a lot to say about BAT but no idea yet
*3 Most like a BCM2079x I2C connected device, an Android driver patch effort is here
