No matter what chipset or gfx you use with the new Atom chip, theTo be more precise, Pine Trail Atoms integrate the entire northbridge, including the integrated graphics and the memory controller into the CPU, and there is a DMI connection to the southbridge, which is the Intel NM10, that is NOT integrated.
integrated memory controller (IMC) will always be used. This patch
checks the presence of that IMC. Hope this clarifies.
What prevents another vendor from selling a compatible south bridge
Nothing (other than licensing for the DMI bus, see NVIDIA and the
problems this creates for their ION chipset). I'm assuming this patch is
checking for the host bridge device though, that is integrated into the
CPU and would always be present.
I start believing that we'd rather identify these Atom models using
CPUID rather than a PCI device.
