Unfortunately you're right and it's not possible :-(.

It's because the front/back/z-buffer are allocated statically at 
startup, with a size to cover the whole screen. I think the idea was to 
change this to dynamic allocation, but afaik nobody is working on it 
currently. Though the pbuffer extension also would require some dynamic 
buffer allocation scheme.
btw what happens if you do fullscreen 3d with the commercial X server (I 
assume XiG summit?) or windows at that resolution? Sounds problematic to 
me...
