In principle, I agree with you. It is possible to hack your kernel, it's just not commonly done for PPC. I used to build custom monolithic kernels all the time under Linux kernel 1.2, but the need diminished as more functionality was added to the kernel and the ability to use modules was added. I've also seen a *few* custom kernels on Hackintosh ISOs, but I've never had or felt the need to hack the kernel myself. I think DSDT hacking is more common, though again, it's not something I've had to do. Maybe I'm "out of touch" with the Hackintosh scene, but I really think Darwin PowerPC kernel hackers are few and far between. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
