I've got 'simple' OpenGL programs running successfully with the VC4 GL driver, but programs that use display lists are not rendering anything except the background colour (although glGetError returns zero). Before attempting more detailed debugging, are there any known issues regarding the use of display lists with the VC4 driver?

Probably best to bug report on Eric's github. https://github.com/anholt/mesa

Re: VC4 driver and display lists
As you were; it wasn't a problem with the VC4 driver. Turned out to be an obscure bug in the ARM edition of my BBC BASIC interpreter, causing the MOD function (modulus of an array) to misbehave, and this was mucking up the 3D computations.
