It just happened again, and this time the backlight did't come back up
after plugging in the external monitor. I had just quit a MOL session when
it happened.
Is there a tool to get a register dump off the Radeon chip? Anything else
to try (add delays in the backlight code for example)? Can the chip have
been stuck in a state with the LVSD_GEN_CNTL register somehow shadowed or
blocked for writes?
