Ok, problem #2 was apparently because I had this in my config file:
Option "PseudoColorVisuals" "on"

Grumble, this took way too long to research but I found the problem:
gandalf:~$ LIBGL_DEBUG=verbose fglrxinfo
libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)
libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/fglrx_dri.so
libGL error: dlopen /usr/X11R6/lib/modules/dri/fglrx_dri.so failed (/usr/X11R6/lib/modules/dri/fglrx_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to find driver: fglrx_dri.so

ln -s /usr/lib /usr/X11R6/lib/modules fixed it.

I also notified:
- glxinfo people to output the useful debug info by default
- the ati folks to do the same in fglrxinfo
- Aric Cyr <Aric.Cyr@gmail.com> who seems to maintain the debian
  fglrx-driver driver

Hopefully this won't happen to too many other people in the future
