I'm pretty sure RDP doesn't actually require any VGA
cards to function, it does it's own thing completely

It sounds like you are losing VNC access once the ATI
driver loads, but the ATI card then ends up not getting
used. I've never seen that happen, usually if something
goes wrong at this point, it's a BSOD which dumps out
to the VNC console on the emulated VGA device.

No I can't. The window freezes during the logo boot screen (which
initially made me think it was freezing on boot). Only access I have
is via RDP or briefly with VNC as it is unpredictable.

I tried disabling and also uninstalling the Standard VGA Adapter. It

Since these settings cannot be changed via remote desktop, I installed
RealVNC... which seems to bork networking for dom0 even and forces a
reboot for me... wonderful.

Anyone else having an issue with their gpu passthrough not using the
card's display headers at all? This is a HVM Windows 7 x64 box.

Can you get to the VM's emulated VNC console from dom0?
