Hello,
The Bug RF-371 (slider: the marker is outside the ruller if it is disabled) is marked as fixed. I have done some tests with RichFaces 3.1.0 RC1 and 3.1.0 Snapshot from 6th August on Tomcat 6.0.13. And the bug is still there.
In version 3.0.1 and 3.0.2 I had this problem just with Firefox. But now in version 3.1.0, I can reproduce this problem in Internet Explorer 6 and 7, too. Only in Opera my disabled slider will be drawn as expected. In Internet Explorer and Firefox 2.0.0.6 the marker is outside of the ruler.

WAR Demo (with RichFaces 3.1.0 Snapshot from 6th August):
