I think this is already implemented, but I didn't tested it though and also can't tell if it still works (and koreader version also must not be too old):

Just to add, I advise before any manual action on settings.reader.lua to make backup of it (in case of wrong syntax koreader deletes it and creates new, default one).

Also, correct syntax for this would be:

["ignore_power_sleepcover"] = true,

notice comma at the end, it is essential.
