From /proc/pci:
Bus 0, device 11, function 0: VGA compatible controller: Matrox Millennium (rev 1). Medium devsel. Fast back-to-back capable. IRQ a. Non-prefetchable 32 bit memory at 0xa0000000 [0xa0000000]. Prefetchable 32 bit memory at 0xa0800000 [0xa0800008]. 0xa080000 is the frame buffer -- according to XF86_SVGA, 0xa0000000 is where the MMIO registers are:
(--) SVGA: PCI: Matrox MGA 2064W rev 1, Memory @ 0xa0000000, 0xa0800000 (--) SVGA: Linear framebuffer at 0xA0800000 (--) SVGA: MMIO registers at 0xA0000000 (--) SVGA: Video BIOS info block at 0x000c7680 (--) SVGA: chipset: mga2064w (--) SVGA: videoram: 2048k
FWIW - It has only been with the very recent 2.1 kernels that XF86_SVGA could properly detect this card. Another owner of one of these systems (HP Vectra XU 6/xxx) discovered that running scanpci prior to starting X allowed the card to be detected properly on earlier kernels!!??
