Description joeo 2001-11-26 21:40:00 UTC 
	AGP functionality for this chipset isn't working with the supplied
	driver.  The page directory needs its entries offset into it
	by an amount determined by the base address of the aperture.

Fix: This patch should correctly populate the page directory with
	the addresses of the gatt tables.  Also the linux driver for
	this chipset seems to indicate that the programatic interface
	for the amd_751 (irongate northbridge part), amd_761 (improved
	part capable of AGP4x operation, socket A?), and amd_762 
	(part of the 760mp chipset) are identical for AGP functionality.

Doug wrote this driver, so he probably has the hardware to test the patch.

The AMD AGP patch was committed some time ago.
