toshiba satellite A300D-21H with ATI Mobility Radeon HD3650 (PCIID: 1002:9591)
osx version 10.5.8 iDeneb 1.6 (with ATY_Init present)
more details about configuration could be found here
applied RadeonHD.kext version "10/17/2009 update", from here
original ATIRadeonX2000.kext was presumably disabled before due to picture absence on display on it's load and conflict with RadeonHD.kext.
rebooted, initially resolution hasn't changed and remained 1024x768, but when
lunched System Preference -> Display, discovered 4 available resolutions, selected right one 1280x1024 and it's working!
QE/CI is not available due to VA/GA bundles not loaded, however they might need ATIRadeonX2000 input first, at the same time FB part of this package should be de-activated.
which is much easier to do with Intel GMA driver, where AppleIntelGMAX3100.kext and AppleIntelGMAX3100FB are different packages/drivers.
anyway, it's a break through progress, great job Dong! thanks a lot!
current version working garanteed only if kext's rescan boot option provided (-f), otherwise it may stuck without switching to graphics and desktop.
possible "magic number" driver priority option is too low?
ATI Mobility Radeon HD3470 as well as ATI Mobility x200, as well as ATI Mobility x1270 (aka X690G) test reports are coming soon (yes, I do have them all ;-).
