[Open-graphics] Problems building S3 and xp10

[Kenneth Ostby]

Hi, 

Finally stuff started to slow down at the university, and thus I started
to look more upon the project again :)

However, I'm having problems building both the XP10 and the S3 toplevel.
When I run iverilog on them Xp10 complains about not finding:
	EHXPLLB referenced 4 times.
	OLVDS referenced 2 times.
	divider referenced 4 times.
Anyone knows where I can find those modules?

I've also submitted a patch to the repository adding a timescale in the
s3_top_level.v, making it pass the compile_s3.sh script.

Kenneth.
