I found the pyramid entrance and got in but am confronted with walls that are covered with hieroglyphics but no button/latch. I tried a few things but to no avail. I looked for a hint through the first 25 pages of Ironworks forum but didn't find a clue. Any ideas?

This was perhaps one of the most difficult levers to find because of where it is placed. As you are entering, go the right and on the side of the big dividing wall (on your left as you would go around it's edge) is the lever.
Given that it is so easy for party members to take damage in lifts and the like you'd think one of your party would have taken damage just walking by the dang thing which would have gotten you to notice it!

Thanks, Wyv! BTW, I have a song called Wyverns on my music CD ("Ziggurat"). It is instrumental but I had a story in mind. It is about an old man telling a story to a young boy about how in the old days wyverns would attack their village. As he is telling the story they attack. I haven't worked out the details of why. I may redo the song on a later CD with vocals. You can contact me at Zigurrat@aol.com if you want a copy (notice the mispelling of Zig). Not sure how to contact you so I'm hanging this out there.
