I'm sure it would be useful to modify your post to include the VendorID:DeviceID of your GPU. Those numbers are how the client determines the GPU. These can be obtained by running gpu-z and looking six lines down for "device ID" or by running fahclient --lspci (with two dashes) or gpu-z. We really can't do anything without more information.
According to the information in the official drivers, the 0x68E1 code does refer to the Radeon HD 6230 and 0x68f9 refers to the Radeon HD 5450. If the manufacturer of your hardware and the official documentation disagree, there's really nothing FAH can do about it. In fact, it really doesn't matter to FAH, however since those two devices are so similar that FAH treats them in exactly the same way.
