Support (accelerated) for the Intel i740 is provided by the XF86_SVGA server with the i740 driver, and for the Intel i810 with the i810 driver. The i810 is supported only on Linux, and requires the agpgart.o kernel module in order to use modes that require more than 1MB of video memory.
Support (accelerated) for the Intel i740 is provided by the "i740" driver, and support for the Intel integrated graphics chipsets i810, i810-dc100, i810e, i815, 830M, 845G, 852GM, 855GM and 865G is provided by the "i810" driver. The i810 and i815 chipsets require kernel-level AGP GART support (available on Linux, FreeBSD, and some other BSDs). The 830M and later can be used without AGP GART support, but it is required for full functionality.
The i740 and and original i810 are supported in both versions, but the i810/i815 is supported only on Linux, FreeBSD, and some recent NetBSD/OpenBSD versions at present. platforms at present.
