With certain boot parameters, you can get from mostly non-functional to mostly functional. dmesg from several combinations of parmeters will be attached, but in a nutshell, with local APIC and IO-APIC and ACPI enabled in the kernel, a lot of strange things happen, even if you use noapic and pci=noacpi. Disabling the APIC helps a little, but to be functional at all, pci=noacpi must be used. Steps to reproduce: Will be detailed in the following attachments.
