Yes, that's expected.

Again,
Option "MonitorLayout" "LVDS,TMDS"
is not really supported yet. The driver will source both heads from the
same CRTC in this case, which can only work if both heads use the exact
same timings. Apparently, it happens to choose the timings which work
for the external display in your case.
I just verified that the exact same 1024x768 mode works fine here on the
internal panel of pretty much the same machine.
Now, what do we do with this report? I see the following options:
* Close as unsupported configuration.
* Turn into wishlist for LVDS+TMDS support.
