Well, I set AGPMode to 1:

agp0: Setting AGP v2 mode 1
info: [drm] Setting GART location based on new memory map
info: [drm] Loading R200 Microcode
info: [drm] writeback test succeeded in 2 usecs
drm0: [MPSAFE]
drm0: [ITHREAD]

Then stopped & re-started xdm several times.  Got a similar lock-up (vs.
last reported one); DDB shows:

KDB: enter: Line break on console
