Hi Alex,

Thanks for all the work on this.

I've actually been using 2.6.32 (Debian x86_64) for awhile and it has been
working okay minus some flaky suspend issues.  If the display is plugged in at
boot time, it turns on my external monitor part way through booting the kernel
and continues to work fine as Xorg starts.

I haven't tried 2.6.35 because Debian didn't release a kernel for it, but they
just released one for 2.6.36 this weekend.  I've upgraded and now it is not
working at all.  That is, the display remains off through the entire boot
process and even once Xorg has started.  Running xrandr at this point says

Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 519mm
x 324mm
   1920x1200      60.0*+
...
DVI-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1680x1050+0+0 (normal left inverted right x axis y axis) 331mm x
207mm
   1680x1050      60.1*+
...
DIN disconnected (normal left inverted right x axis y axis)

and "xrandr --output HDMI-0 --off" followed by "xrandr --output HDMI-0 --auto"
does not turn it back on.

Cheers!  -Tyson

PS:  It likely doesn't matter as this shows up before xorg even starts, but I'm
currently running xorg 7.5 and xorg radeon driver 6.13.1.
