Answering my own question, it gets its info from the XINERAMA
extension, which can be queried like this:
xdpyinfo -ext XINERAMA
The heads showing up there determine the heads used in fluxbox.
Apparently the fglrx driver doesn't enable XINERAMA by default, so it
has to be done manually, in the ServerLayout section of xorg.conf:
Option "Xinerama" "True"
