VIA (694X) (Gigabyte 6VXD7), G450, XF4.0/XF4.1, SMP (2xPIII/833) works
fine if you
(1) do not use matrox module from Matrox and
(2) there is not PCI activity which targets G400 when X initialize
hardware (during start or console switch) and
(3) it is highly unrecommended to use DRI (as it touches G400 hardware
even when X are not on foreground)

If it is too limiting for you, look for another chipset. With i440BX
you'll get at least 2x faster PCI->AGP transfers than with VIA: i440BX
can handle 60MBps (32bpp full PAL) without any problems, while 694x has
problems with 30MBps (16bpp full PAL) (IDE disk accesses are visible
as dropouts on picture).

There is nothing Linux kernel can do for stability of such box.
