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!!??
