Hi all,

I'm suffering from bug 28 [1], unable to assign more than 3.5 gigs of RAM to my Windows VM while using VGA passthrough. This is a showstopper for me.

Since #28 is still listed as up for grabs for 4.5 [2], I assume a fix is not likely to make it in. However, a message from Ian [3] indicated that a workaround was available at some point. Will a workaround be offered for 4.4 or 4.5?

I'm using Xen 4.4.1 on Debian Jessie (official distro packages), kernel 3.16, Xeon 5660, Intel 5500 chipset (rev 22), Nvidia Quadro FX 4800 GPU.
