I updated my Dell E521 (iPC 10.5.6) via Software Update to 10.5.7, I had to reboot to the iPC DVD and copy over the mach_kernel (I made a backup before running the update), remove the "new" nVidia kexts and put back 10.5.5 via 9f23installer, removed AppleHDA.kext in favor of VoodooHDA.kext. Working well!
