I think this limitation is due to some Xorg configuration parameter. I
think that with a Screen section with a larger virtual resolution you
can solve this, as in this excerpt:

Section "Screen"
        Identifier      "Default Screen"
        SubSection "Display"
                Virtual         3360 1050

(Here, it's calculated for two 1680x1050 monitors side by side; do the
math for your 1024x768 + 1920x1080)

BTW, the “Open Firmware” limitation is just a hint for the OS, I think;
you can get larger resolution in linux without this hack. It's just a
soft limitation.
