Instead just initialize the memory type parameters

Hm what's the motivation here? I do agree that the init_mem_type callback
is rather midlayer-y (having a per-type cast in a callback is a very clear
signal something with the layering is all busted). So removing this sounds
like a good idea, but not really following why just for radeon? Or simply
wip?
On the first try only the first 3 mails made it to the list and then my
internet connection crashed.
I've send out the full set a minute later once more.
Christian.
