My computer is a notebook.  I'm not aware of any way to replace the 
video chip.  I wish I could, because it is a crappy chip.  Do you know 
of a way?  PCMCIA perhaps?  Docking station?

I'm not running X.  I'm trying to play movies without X because I'm not 
happy with mplayer's playback under X.  Here's some info about svgalib: 
http://www.svgalib.org/vibber/svgalib-dev-faq-2.html

I've also tried -vo fbdev and I'm ALMOST satisfied with it.  I'm trying 
svgalib just in case it works that tiny bit smoother.
