I didn't see anything obviously wrong, but it is often the case that 
even though the hardware might be similar to what other people are 
using, the BIOS may be very different and/or very broken. The vBAR=pBAR 
approach works around some issues caused by BIOS or hardware bugs, hence 
why I thought it might be worth a try adapting those for your system.
