Were they wrong and I should add pci/agp_i810.c back? My understanding is that, this driver needs to be enhanced to support the 915G chipset: #define CHIP_I810 0 /* i810/i815 */ #define CHIP_I830 1 /* 830M/845G */ #define CHIP_I855 2 /* 852GM/855GM/865G */ Also, agp_810.c may be a little bit of a misnomer for the file, given that it seems to support other chipsets. This is true of the xorg i810_drv.o as well. Even though the name suggests only i810, it really supports a range of chipsets including the 915G: http://cvs.freedesktop.org/xorg/xc/programs/Xserver/hw/xfree86/drivers/i810/i810_driver.c?rev=1.13&view=auto -Arun
