Hello everyone, there's a possible solution from J=FCrg Billeter, on http://bugzilla.kernel.org/show_bug.cgi?id=3D3022. He suggests to remove the CONFIG_PPC_PMAC condition in drivers/video/aty/radeon_pm.c. Doing so, he reduces the power drain of his = T40p. This works for me. On my T40 (radeon 7500) power drain went from 2.7 W to 0= .8 W Michele
