I have just installed 10.5.6 with vanilla kernel on the Intel board DG33TL with the CPU E8400. And I have a few problems:
1) CPU runs on incorrect speed - it runs on 2GHz instead of 3 GHz. (In the 'About This Mac' dialog I see : "2GHz unknown", CPU-x says the same number - 2GHz)
2) Sleep mode doesn't work - when I tried it - it MAC tries to sleep, screen goes to black, but all fans are still works and there is not any way how to turn PC/MAC on... Maybe I must have some ACPI fix?
Can anybody help me, please? I tried to find something on the web and this forum, but... because I'm novice in this area still without luck.
