I remember I did some experiments about remapping the axes to a more meaningful setup and there were some improvements but that work depended on some experimental changes to the linux input layer from David Herrmann (the ABS2 proposal) and I do not know if the latter ever reached mainline.

JFYI a possible hardware way is to keep pushed the PS button for some seconds, this also should turn the sixaxis off.
