There are some issues with access to more than 128 MB on radeon cards.
 from the latest code drop:

/* There are different HDP mapping schemes depending on single/multi
funciton setting,
 * chip family, HDP mode, and generation of HDP mapping scheme. 
 * To make things simple, we only allow maximum 128M addressable FB.
Anything more than
 * 128M is configured as invisible FB to CPU that can only be accessed
from chip side.
 */

the code also limits the cards to 128 MB for now.
