I've never used it, but I've seen references to pcigart, which provides (some of) the features of the agpgart kernel module for PCI devices. After a quite google, I'm not sure whether it is actually a kernel module, or part of the Mach64 DRI project: http://www.ussg.iu.edu/hypermail/linux/kernel/0102.1/0959.html suggests that it may come with the DRI, but http://mail-index.netbsd.org/tech-x11/2003/03/19/0006.html suggests that it may come with the OS kernel. (The first is quite old, but sugegsts that at the time pcigart may not have had support for the Mach64). My Mach64 is about 5 years old, and I've never needed a kernel module for it, but I know that some of the later, more integrated, versions were somewhat different. As Tim Roberts says, even with system memory, you may not need the gart functions, if the BIOS allocates enough memory to the graphics unit. Since you are on a custom platform that may or may not help you. -- Andrew C.
