Hoyle's ideas about steady state theory, abiogenesis and Archaeopteryx have already been described in this thread. The Wikipedia entry on Hoyle offers a pretty good summary. But realize that creationists will tend to interpret his later ideas in a positive light. This is because they'll, for instance, approve of challenging the authenticity of the Archaeopteryx fossils and ignore the shabby scientific grounds upon which Hoyle based his challenge.
I'm not familiar with Hoyle's Archaeopteryx argument, so I cannot currently defend or criticize it. If you have any information on it, I would like to read up on it though.
As far as creationists lauding Hoyle, it seems like an odd fit. I mean, Hoyle was an atheist and an indirect panspermist. That's not exactly a match made in heaven-- no pun intended. But it seems that as long as someone will defy evolution and the big bang, many YEC's will gladly support their points.
Which is another thing. I've never really understood why YEC's have a problem with the BB. I mean, Hoyle was repulsed by the notion that the universe had a beginning at the singularity. And creationists say that the universe had a definite beginning. So why the controversy? I've never understood that.
