 If you had OpenGL, Gnash should build for this architecture. My gut 
feeling is this would be too underpowered to run OpenGL adequately 
unless you have a pretty good graphics processor, or do very simple 
movies without much animation.

  This is the main reason I want to replace the OpenGL backend with a 
framebuffer one... This would be a great project for somebody, but it's 
going to take awhile before I have the chance to do this. Once Gnash has 
good backend framebuffer support, then you wouldn't need OpenGL. 
Typically system like this only have framebuffer support and no real 
graphics processor.

  One of the goals of Gnash is to run on truly embedded systems like 
this so it can be used for the GUI. Right now our priorities are 
stabling Gnash (this is a new project, and under heavy development), 
implementing critical functionality, and attempting to beat the Firefox 
plugin into shape. So for now, "embedded GNU/Linux" translates to about 
800Mhz Pentium class processor with some hardware acceleration support. 
I have used the i810 and i815 as the low end of what works as a graphics 
processor, although the this graphics processors has major bugs with 
it's DRI implementation and leaks memory bad...

  This is all in the Gnash manual. There is an entire section on 
dependencies.

  Libmesa is the free implementation of OpenGL. Since Gnash uses the 
GNU autotools, you should be able to cross compile it with no problem. 
You just have to set --host, --build, and --target appropriately when 
configuring.
