glxinfo lists visuals in the "gaps" between the ones listed above. 
There's visuals at 0x24 and 0x26 for example.  I am running the Mesa CVS 
version now, but I haven't rebuilt x.org against it.  I get some other 
errors from glxinfo, the largest of which is that it's trying to use the 
dri module from my old X install.  I can't figure out how to get it to 
use the new one.  Here's the errors I get when I run it:

libGL error: dlopen /usr/X11R6/lib/modules/dri/updates/i915_dri.so failed 
(/usr/X11R6/lib/modules/dri/updates/i915_dri.so: cannot open shared object 
file: No such file or directory)

ERROR!  sizeof(I830DRIRec) does not match passed size from device driver
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering
