xorg crash in InitOutput() after upgrade to 9.04 from 8.10

[Gleepwurp]

System was upgraded from Ubuntu 8.10 and is running from within a VirtualBox VM.... System reported Xorg crash and had trouble running under display :0 and had to run under :1... Don't know if that helps you guys with the Alpha Development of 9.04... Let me know if I shouldn't do this... :)

Looks very similar to bug #335703 although traces don't match.
Maybe this should go upstream next?
