The AMD-V mode is not working anymore. I have a HP 6715b NB with Turion64-X2 2.0 GHz and ATI X1250. The ATI X1250 has problems when running VMs, but it worked on prior VBox when the AMD-V mode was enabled. When I enable the AMD-V mode now, the VM will not even start to boot (the Sun xVM Logo does not appear). So it doesn't matter, which VM (Win2000 or kubuntu) I start.
