Hi!

X stops working for my setup with newest ddx from git master.
The following message precedes the segfault:

(EE) RADEON(0): Couldn't allocate shadow pixmap for rotated CRTC

I'm using libdrm from git master and xorg-server 1.11.4
on a Radeon X300 graphics adapter with two displays attached.
One of the displays is rotated (see xorg.conf as attached).

Unfortunately I won't have time to bisect but this configuration
worked as expected with ddx from git master as of 2-3 days ago.
There is also no such issue with 6.14.3.

Thanks in advance for looking into this!

PS. On a side note:

(EE) RADEON(1):  reusing fd for second head

What does this *error* actually mean?
It also present in the working configuration.
