here it's

(II) RADEON(0): initializing int10
(==) RADEON(0): Write-combining range (0xa0000,0x20000) was already clear
(==) RADEON(0): Write-combining range (0xc0000,0x40000) was already clear
(II) RADEON(0): Primary V_BIOS segment is: 0xc000
(==) RADEON(0): Write-combining range (0x0,0x1000) was already clear
(--) RADEON(0): Chipset: "ATI FireGL Mobility T2 (M10) NT (AGP)" (ChipID = 0x4e54)
(--) RADEON(0): Linear framebuffer at 0xe0000000
(II) RADEON(0): AGP card detected
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
