I have tried replacing DOMID_IO with DOMID_LOCAL, and then the call goes through, but I have no idea if it makes any sense doing that. By the way, I just tried with an Nvidia graphics card in the machine, and the problem is the same, so it must be a problem with the chipset which is an Intel i875. The machine is a Dell Precision 380 workstation-class machine with a P4 3.2GHz and 1GB mem.
