OK I have upgraded to iATKOS 10.5.1. When I use the files posted by Zaiden in #122, I get a blue screen at boot, with a "ghost" cursor that doesn't move as well as a real movable cursor. But the screen remains blue with no other graphics ever printed to the screen.
If I replace just the ATIRadeonX1000.kext with the original, I get booted normally, but the system profiler says this:
ATi Mobility Radeon x1700:

Does anyone have an idea what I am doing wrong?
