New and old one works fine with Paul's patch: --old-- agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0. agpgart: X tried to set rate=x12. Setting to AGP3 x8 mode. agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode ------- (ok, so old driver is a bit dodgy) --new-- agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode ------- -- Martin Schlemmer
