Bug #604: 1.8.1-RELEASE - clock runs fast on mainboard ASUS P5A-B

* Author: yeti
* Status: In Progress
* Priority: Normal
* Assignee: 
* Category: ACPI
* Target version: 4.0.x
After a fresh install of 1.8.1-RELEASE on a system with ASUS P5A-B
mainboard (ALI chipset), the clock runs twice as fast as normal.

Booting with ACPI disabled solved this problem.

The clock problem on some ATI chipsets was a problem in Linux some
kernels ago too. The solution was triggered by clock=pit as bootarg if I
remember right... maybe having a peek into Linux's code helps.
