PX = PowerXpress. PX systems are laptops with two GPUs, an integrated and a
discrete GPU.

It does not disable power management. It only disables the special handling
for PX systems which gets incorrectly applied to non-PX systems in certain
cases. When you apply the patches you shouldn't need to add the radeon.runpm=0
option. If radeon.runpm=0 fixes the issue, so should the patches.

If you are using git:
git am
Otherwise:
patch -p1 -i
