Patch to support newer VIA graphic chipsets in kernel drm
Currently newer VIA graphic chipsets including CN700, VM800, P4M800Pro, P4M890, K8M890, CX700, P4M900 and VN896 are not supported by the kernel drm, even though they can already be supported using existing code.
This problems has always existed in RHEL <= 5.5
The attached patch is based on via drm code in latest kernel. Apart from adding the missing PCI ids, it defines a new class of display engine VIA_DX9_0, which is identical to VIA_PRO_GROUP_A but has no 3D capabilities.
The changes made by this patch are localized to via.ko, and does not impact other modules. Support for existing VIA graphic chipsets are also unaffected.
