I noticed that I miss some messages sometimes, sorry.
I'm not linux dev and reading/parsing some files to get temps looks strange for me and will take some time to implement and test it properly. Therefore I will not do it right now, though I will do it in future anyway because it seems there is no "normal" way now, again thanks to AMD devs, they don't care about such things as backward compatibility. Also, this way allows monitoring only, fans management won't work.
Right now I add new coin and I think it's more interesting feature than getting temps for Linux for 4xx cards.
