'That' annoying hang? Have I missed something? *shrug*

I suspect that you've been chasing red herrings, my bet for the
mysterious symbol is on drmCommandNone(), which gets resolved by the
server's dynamic loader (or doesn't, when the DRI is disabled). Build a
static server to get reliable debugging info, but I doubt it'll help for
the actual problem:
