I just want to add, that I know that agp in working with the 2.6.17 kernel because:
1. cat /proc/drivers/nvidia/agp/status is showing that agp is enabled at 8x (it is disabled with the 2.6.15 kernel) and 2. I get 12000-13000 fps with glxgears (5000 fps with the 2.6.15 kernel) The 2.6.17 kernel sources have this new via-agp for via 880ultra driver that was absent in the 2.6.15 kernel. Previously, in dapper, I have manually patched the 2.6.15 kernel with the new via-agp and agpgart drivers extracted from the 2.6.17-rc, 2.6.17-mm and 2.6.17 kernel tree. The result with this patched 2.6.15 kernel was the SAME as with the 2.6.17 kernel (agp was working, but I had freezes and kernel panics). -- system freeze/kernel panic with kernel 2.6.17 (probably due to via-agp) https://launchpad.net/bugs/53772 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
