I am also seeing this bug.

Machine specs:
Compaq Alpha XP1000 (667MHz EV67 cpu)
Powercolor HD 2400 Pro PCI (RV610)

I have patched rhd_id.c to contain a line specifying the monitor connection
details for the powercolor graphics card onto the git commit just before the
DRI stuff was checked in (possibly at commit 4f3d627795ab).

Starting X leads to a black screen. The monitor reports that is receiving a
signal of the expected resolution and sync frequencies. This occurs for both
the vga and dvi outputs.

Shutting down X leads to a complete system lockup. No response with ping.

Applying the following before starting X (as suggested in comment 17):

/sys/bus/pci/devices/0000:01:00.0 # echo 1 > enable
/sys/bus/pci/devices/0000:01:00.0 # echo 1 > rom
/sys/bus/pci/devices/0000:01:00.0 # cat rom

works! X starts up with proper screen output. When I close down X (or attempt
to shift to one of the text consoles with ctrl-alt-<num> the system locks up.
Again no reponse with ping.

I attach two log files. One from the example of the black screen and one when
X starts up with output.

(Attachments appear to have gone through as previous messages - it is not
obvious from bug logging system that this would occur.)
