I've a strang problem with my onboard nic. Its running only booting without -f Flag, if I place the kext outside the IONetoworking.kext. And sometimes, it is suddenly not recognized and I have to reboot. Also standby doesn't work quit as excepted, because after waking up, I've a cracking sound in the speaker, about every minute. Any advice?
I had the same problems. There have been some changes in the last few releases (I'm up to 10.5.5) that don't seem to agree with my mobo architecture. I've abandoned the onboard NIC for a PCI 3Com NIC. Strings are not working as expected either. It seems like sometimes they are ignored at boot time.
The sound problem has to do with timing. Using a different version of Taruga's patcher solved the problem for me.
