Is there anything reported on /var/log/XFree86.0.log or
/var/log/messages?

The 3 * screen size restrition refers always on the video memory.

Yes. Either start X with gdb or attach gdb after X starts but before
changing resolution from a remote terminal, e.g.:

28952 ? 02:49:17 X

Then reproduce the segfault, i.e., change the resolution in this case,
the gdb command line should reapper. Type 'bt' and post the result.

I didn't followed you. What do you mean with SW rendering and which two
situations do the difference in fps refer?
