There are more options you can pass to the kernel related to ACPI/APIC 
subsystem:

I still think is is an ACPI issue more than hardware (mouse/keyboard) or 
a VGA driver problem. But to start discarding culprits you can try to:

- Use a different VGA driver (if possible)
- Test with another DE or WM (this can be also tried from a LiveCD)
- Review the logs
