Thank you for this very helpful response. This is what hwinfo says:

       Model: "ATI VGA compatible controller"
       Vendor: pci 0x1002 "ATI Technologies Inc"
       Device: pci 0x6759 
       SubVendor: pci 0x1682 "XFX Pine Group Inc."
       SubDevice: pci 0x3190
       Memory Range: 0xd0000000-0xdfffffff (ro,non-prefetchable)
       Memory Range: 0xfe7c0000-0xfe7dffff (rw,non-prefetchable)
       I/O Ports: 0xb000-0xbfff (rw)
       Memory Range: 0xfe7a0000-0xfe7bffff (ro,non-prefetchable,disabled)
       IRQ: 16 (412396 events)
       I/O Ports: 0x3c0-0x3df (rw)
       Module Alias:
            "pci:v00001002d00006759sv00001682sd00003190bc03sc00i00"
       Driver Info #0:
       Driver Status: radeon is active
       Driver Activation Cmd: "modprobe radeon"
       Config Status: cfg=new, avail=yes, need=no, active=unknown
       Attached to: #14 (PCI bridge)

but since /libdrm-2.4.33/radeonr600_pci_ids.h from wheezy already includes:

       CHIPSET(0x6759, TURKS_6759, TURKS)

it seems like the chipset should be supported in that version. The
ones that were added in the commit you referred me to are:

       +CHIPSET(0x6751, TURKS_6751, TURKS)
       +CHIPSET(0x675B, TURKS_675B, TURKS)
       +CHIPSET(0x675D, TURKS_675D, TURKS)

Thank you for this help also.

Good luck with your work,
