Xorg 7.3 causes kernel panic

I'm experiencing the same problem described in this message:  http:// 

The system is an Ultra 60 with two 450MHz processors.  Two  
framebuffers (one Creator3d, one m3) are installed.  The full dmesg  
is at the end of this message.

After building the newest x11/xorg port, the kernel panics whenever  
Xorg is executed.  6.9 worked fine.
Here's the backtrace from the crash:

Unread portion of the kernel message buffer:
panic: trap: memory address not aligned
