OK, now I feel stupid. Your command is ran as root, I wasn't doing that.
However, there's another problem now:

# ./atiflash -ai
Adapter  0    (BN=01, DN=00, PCIID=69001002, SSID=811C103C)
    Asic Family        :  Iceland        
    Flash Type         :  R600 SPI    (64 KB)
    No VBIOS

# ./atiflash -s 0 hpatombios.bin
