X server log

I'm experiencing a problem with output blanking on both XOrg server 1.4.2 and
1.5.0.  I'm using Gentoo Linux with vanilla kernel 2.6.26.5 (back through
2.6.25 at least) while using stable and git releases of the radeon driver. 
X1650PRO (RV535).  I have kernel drm compiled as a module.  I'm not attempting
to insert it at any time during boot, so I'm assuming that XOrg drm is taking
precedence.

Scenario 1:

* server 1.4.2

I can enter graphics mode exactly once per boot.  Linux starts, xdm initscript
starts gdm, I can log in, I can switch from the X vt to the text console vts
and back.  If I shut down X and attempt to restart it, X crashes and leaves me
with what I think is a working text console, but both the CRT and DVI-I outputs
are blanked.  I can shut down gracefully with Ctrl+Alt+Del (/sbin/reboot) or
the power button (acpid handler).  X works fine again after a warm boot, but
only once, as before.  No log output whatsoever.

Scenario 2:

* server 1.5.0:

X starts fine, or appears to.  I'm attaching a log.  Logging in from another
machine via ssh shows various X components running.  However, there's no output
on either graphics port despite messages showing what appears to be successful
output blank/unblank.

Note that, although the card has TV output, I'm not using it.  I have an LCD
panel attached to the VGA port.  IIRC, this problem started occurring when I
switched from an X800GTO (R423) to the present card.
