So if you have 512 MB of memory (as I do), a working value will be at least 0x20000000. It might need to be higher. For 768M, start at 0x30000000 and if you have 1 GB, start at 0x40000000. I have 512 MB and set it at 0x20000000. I see agp at 0xe0000000, cbb0 at 0x50000000, cbb1 at 0x51000000 and fxp0 at 0xd0200000. I I tried starting at 0xd0202000, I would not have space for everything. You may also need hw.pci.allow_unsupported_io_range="1". -- R.
