Hello,
could be that this code from /drivers/char/agp/agpgart_be.c is bogus:
case PCI_DEVICE_ID_INTEL_830_M_0: i810_dev = pci_find_device(PCI_VENDOR_ID_INTEL,
PCI_DEVICE_ID_INTEL_830_M_1,
NULL); ===> if(PCI_FUNC(i810_dev->devfn) != 0) { i810_dev = pci_find_device(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_830_M_1, i810_dev); }
if (i810_dev == NULL) { printk(KERN_ERR PFX "Detected an " "Intel 830M, but could not find the" " secondary device.\n"); agp_bridge.type = NOT_SUPPORTED; return -ENODEV; } printk(KERN_INFO PFX "Detected an Intel " "830M Chipset.\n"); agp_bridge.type = INTEL_I810; return intel_i830_setup(i810_dev);
