This is because your modelines aren't set correctly under XFree86. (As I said

It is not specific of your hardware, but due to your set up.
As I recall, you have X 3.3.6, which means that setting up your modelines is
a bit tricky (so it's no wonder that they aren't set correctly... this is one
of the last great arcane X issues to be resolved by the 4.0 release ;-)
But basically, you want to look in your XF86Config file (which is usually in
/etc/X11) and find the "Modeline" lines. What you should have is a serious of
settings for various resolutions (really, any resolutions you want to
support). Here's what mine used to look like in X 3.3.6:
Modeline "1152x864" 135.00 1152 1456 1584 1760 864 864 876 908
Modeline "1024x768" 65.00 1024 1068 1212 1248 768 779 785 870
-hsync -vsync
Modeline "800x600" 50.00 800 820 940 1068 600 601 607 622
+hsync +vsync
Modeline "640x480" 31.50 640 652 716 840 480 481 484 500
-hsync -vsync
Then you want to check and make sure that all resolutions you want to support
are listed in your "Screen" section. Again, mine looked like this in X 3.3.6:
Section "Screen"
Driver "accel"
Device "Sam's Card"
Monitor "Sam's Monitor"
DefaultColorDepth 16
Subsection "Display"
Depth 8
Modes "1152x864" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection
Now, figuring out your modelines is the real hard part, and I'd recommend
taking a look at the "Video Timings Howto":
http://www.linuxdoc.org/HOWTO/XFree86-Video-Timings-HOWTO/index.html
You might also want to try and learn how to use "xvidtune" (which should
already be installed) which can allow you to tweak these settings and which
spits out the modelines ready for you to insert into your XF86Config file.
However, if you update to X 4.0, you probably don't need to worry about all
of this junk. X 4.0 is supposed to take care of this for you.

If your fullscreen mode was setup properly, and if your hardware is
supported, you'd see a noticable difference in performance.
