I can't try it right now, but I believe that there's something wrong with the
reprogramming of the lanes count; please note that lspci *always* report:

LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt-
ABWMgm-

At the end of RADEONSetPCIELanes link_width_cntl is 0x000096 (LC_LINK_WIDTH_RD
is 1) - regardless of the width requested (I was trying to force 16x).
