I readded DT2W (based on the original one by Christian and with Vlad's updates) for my extended kernel and I get two (old) issues.

1. sometimes it doesn't wake up after touching
2. sometimes (very rarely) the screen becomes extremely unresponsive, to the point it is totally unusable. I originally thought that this was related to some recalibration issue, due to the fact that the touch sensor is kept on all the time. But this time it happened from one second to another while I was using it.
   Disabling DT2W solves the issue (after you turn the screen off an on) instantly.

This is the log after the second issue (showed the same after the first one):

I was able to confirm that bug reported on XDA! Basically you can only charge the device once per boot. If you want to recharge it again later (about 12h or so), the current gets limited to 100mA, which is so low that it refuses to charge at all. We didn't catch that, because we reboot too often. Took me 2 weeks and many mails with an XDA member to even confirm and replicate it. Logs don't give a clue why it is happening either.
The current charger implementation is a mess, and probably needs to be revised again. Until I found a fix, I don't think any new public release makes any sense..
