Indeed.

The O2 owner's manual is available as pdf from sgi.com

No and no.
The driver isn't broken, XFree's loader for sgimips is.
You need to load wsfb's dependencies by hand, using something like this:
     Load        "fb"
     Load        "shadow"
in your XF86Config's "Module" section.
That should take care of the missing symbols.
You can find mine here:
ftp://ftp.netbsd.org/pub/NetBSD/misc/macallan/sgimips/XF86Config.sgimips

There's one caveat though - gtk2 applications will dump core due to a  
bug in Cairo - it can't cope with the O2's RGBA pixel format for some  
reason, a bug report has been filed but there is no solution yet.  
Other things like windowmaker, KDE etc. work fine.

have fun
Michael
