Notice: I've updated the file tools/firmware/hvmloader/acpi/dsdt.asl
for my graphic card (MSI GT 440 1024), so please update the file
tools/firmware/hvmloader/acpi/dsdt.asl according to the required memory reservations
of your graphics card.

Get it using lspci |grep VGA. Ensure to use

dmesg | grep pci (depends of required modules for PCI debug in your kernel

Find the required fields

Update the file.

I did not succeed to use my graphic card EVGA GTX 460 1024M. If someone succeeded, it will be 
great to tell how he did :)
