        I've got two Linux boxes with kernels compiled with AGP support, as a
module. For box A I have the following in my logs:

Jan 29 10:41:56 A kernel: Linux agpgart interface v0.99 (c) Jeff Hartmann
Jan 29 10:41:56 A kernel: agpgart: Maximum main memory to use for agp memory: 431M
Jan 29 10:41:56 A kernel: agpgart: Detected an Intel(R) 845G Chipset.
Jan 29 10:41:56 A kernel: agpgart: Detected 8060K stolen memory.
Jan 29 10:41:56 A kernel: agpgart: AGP aperture is 128M @ 0xf0000000

        The logs in box B contain the following:

Jan 26 13:46:39 B kernel: Linux agpgart interface v0.99 (c) Jeff Hartmann
Jan 26 13:46:39 B kernel: agpgart: Maximum main memory to use for agp memory: 439M
Jan 26 13:46:39 B kernel: agpgart: Detected Via Apollo Pro KT133 chipset
Jan 26 13:46:39 B kernel: agpgart: AGP aperture is 64M @ 0xd0000000

        In A, the agpgart module seems to be used

A# lsmod

agpgart 24552 6 (autoclean)

whereas in B I get

B# lsmod

agpgart 13840 0 (unused)

        Why the difference? The graphics board on A is an Intel 82845G/GL,
whereas on B it is an Nvidia Riva TNT2 Model 64.

        What am I missing here?
