It took me a while before a got all together, don't give up because it might take more than an hour. If all is done accd to initial post, keep changing atiframebuffer until you get it right. It took me a couple of dozen reboots and changes till i got it working.
atiframebuffer? I'm guessing you mean Hoolock, Vervet, Eulemur and so on?.. the problem is i only know those 3, i had a page up with them all listed earlier but lost it.
so far none have worked. I'm a little confused about the <key>UseAtiROM</key> in that do i use it at all or not?
so far, with Hoolock the os began booting but stopped at some point (didnt use -v so didnt pinpoint it, will do at next boot) but when i held my power button down it made a Mac system sound :s.
with Vervet the boot stops after some text about my card, but it does acknowledge that my card is a Radeon HD 5650 Mobility card so its promising.
with Eulemur the boot just failed.[EDIT]
this method does work in Leopard, the video card is recognised but my laptop just stays in verbose mode instead of reaching the desktop (if i boot without -v then it just stays as the grey apple screen).
I can VNC, using LogMeIn, and checked system profiler where it stated my HD5650 card and i could change resolution. but cannot change it to 1366x768 and switchresx isnt being helpful at all. i changed the resolution to 1024x768 but nothing happened on my laptop screen, it just stays in verbose more listing the system actions. for example if i close an application it says applications dead: 1
can anyone help, i've tried every FB but it doesnt make a difference, none boot on my laptop screen but most are available through VNC, others dont load or give me kernel panic
