Might want to clarify that there is no loss of functionality here.
Something like:
"There is no loss of functionality here. GPUs will continue to
function. This just drops the use of the AGP MMU in the chipset in
favor of the MMU on the device which has proven to be much more
reliable. Due to its unreliability, AGP support has been disabled on
PowerPC for years already so there is no change on PowerPC."
With that updated, patches 1, 3:
