$ lspci -n | head -n 1
0000:00:00.0 0600: 1106:0308
In kernel source i have put in the file ./include/linux/pci_ids.h
#define PCI_DEVICE_ID_VIA_PT880 0x0308
#define PCI_DEVICE_ID_NVIDIA_QUADRO_FX_2000 0x0000
Now:
$ dmesg | grep agp
Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected VIA PT880 chipset
agpgart: AGP aperture is 512M @ 0xc0000000

agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode
and all works ok.
I don't find the mail of agpgart's maintainer.
