I don't really know... 2.4 and 2.6 kernels have a config option for each. 
I'm using the Ati proprietary driver and if tmpfs is not mounted on /dev/shm, 
3D apps like armyops or fgl_glxgears (a special glx_gears contained in the 
Ati driver download) show errors like:

FGLTexMgr: open of shared memory object failed (Function not implemented)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!!

and either run extremely slow (fgl_glxgears) or crash (armyops). The "normal"  
glx_gears is however not affected by this.

With best regards,
