Composite sync could be generated with a very small circuit (one linear
transistor, one XOR and few resistors).
Don't remember exactly how to do it, but I connected an Apollo fixed sync
monitor to my PC box with one I built in the past.  I don't have it handy now
because I gave it to a friend of mine.
Search for the Apollo FAQ.  I got it there.

btw, you can use svgatextmode to create a text mode with the right refresh
rate.  It supports kind of modelines like Xfree.
