It permits the extra features of an AGP port which will otherwise behave
like a PCI device (iirc).  This means the extra bandwidth for shuttling
textures and the enhanced clock rate.

That goes in the driver section of your XF86Config-4 file.  You'll need
something like

Options "AGPMode" "4"

though the config option name differs between the various drivers.  It's
usually documented in their manual page though.  Have a read, and if
that fails "strings" the driver and look for the config options, it'll
be obvious :)

Just one note on this - get it right.  At least with the matrox driver
if you choose a value which is unsupported on your system, it'll fall
back to 1x mode.  Better than nothing, but probably not what you expect.
