And I have the same problem after updating X.org on the both my
machines: 7.1-RELEASE/amd64 and 6.4-RELEASE/i386.
The 'X -configure' command produced wrong config. And even after
removing all incorrect records in it - this is take no effect. I
continuously updating ports and rebuild the X.org server when
modifications appear. The question is to better downgrade to
previuos version that work fine or wait a pathes?

ps.
The 7.1-RELEASE/amd64 PC have Radeon X300.
The 6.4-RELEASE/i386 PC have GeForce 4 MX 440.
