User add-on driver does not have precedence over system add-on driver
|Reported by:||gerald zajac||Owned by:||axeld|
|Has a Patch:||no||Platform:||All|
If two drivers support the same device, the one installed as a user add-on should take precedence over the one installed as a system add-on. For example, if there is a video card with a Savage chipset, it will normally cause the s3savage driver which is installed as a system add-on to be loaded and used. However, if another driver named S3 supports the same chip and is installed as a user add-on, it should take precedence and be loaded and used instead of the system add-on driver, but this does not happen. The following lines from the syslog shows both driver are loaded, and the one installed as a system add-on is opened.
