    Seems like the Radeon HD 5770;  codenamed  Evergreen (R800) is not 
supported by Xorg's radeonhd driver:


    The /radeonhd/ driver supports video cards based on

    * R500 style hardware: R5xx, RV5xx, RS6xx, RS740, M52 and up
    * R600 style hardware: R6xx, RV6xx, RS780, M64 and up
    * R700 style hardware: RV7xx

   OI booted with GUI on my gentoo workstation with a RadeonHD 4670 
(R700 chipset)
   I can only suggest to downgrade to an R700 based card.
