I have this board, and while I'm not using Fedora Core, I've had similar (if not the same problems).
On boot, add the options "acpi=off" and "noapic" to the kernel boot options. This may get it working for you.
Sure, disabling the power management control really sucks (as such the computer can't even turn itself off), but it's better than not runing at all.
Also note, unless you have kernel version 2.6.11 or higher the system will run horribly slow... but I'm sure you do, otherwise you probably wouldn't be having the problems you're having.
