There seems to be a problem with recognizing the ati-card as a mobility-firegl-V5700; instead it is seen as a HD3650, which is slightly different, resulting in different drivers.
Bios upgrade to >1.18 fixes this; then also a new driver for the firegl is needed instead of the hd3650 driver...

link to bios-update

explanation etc.
