I also have an intel mobo with an 845G in it, with a Radeon 9800pro in the
AGP slot. I don't have any troubles with this, so let's see if I can help any.

Have you tried disabling the adapter or uninstalling the driver through
Device manager? Right-click "My Computer," ckick on the "Hardware" tab, and
click the "Device Manager" button. Expand the "Display Adapters" group, and
find the intel adapter. Right-click on it and either choose "Disable" (to
disable the device) or "Uninstall" to uninstall the drivers for it. I would
go with the uninstalling of the drivers, myself.

See if that helps!
