I have kinda Install problem:
Install disk: 10.5.2 v2 Zephyroth
Hardware: cpu: Opteron170
Mobo: DFI NF4 Ultra-D
HDD: IDE 250Gb Maxtor
VGA: Galaxy 8800gt 512Mb

Problem detail:
If I boot with install disk, system will boot normally.
Without install disk, I am getting cpu panic which says: " Unable to find driver for this platform: \"ACPI\" .\n"@/Volumes/disk1s2/leo_xnu/xnu-1228/iokit/Kernel/IOPlatformExpert.cpp:1405

Can somebody help me with this problem?

Update:

I found a solution. I havent installed LAN card drivers, and my system booted normally.
Also AppleACPIPlatform.kext has dependecies which results in kernel panic if, like in this example a specific hardware is installed.
