    How about downloading and building a kernel.org kernel? I have no problem on my ASRock E350M1 using 2.6.38_rc6
    The firmware files can be downloaded from here, too: http://people.freedesktop.org/~agd5f/radeon_ucode/

    btw. your new dmesg looks like bug 34137. Workaround: Option "EnablePageFlip" "false" in xorg.conf

    Looks like these got lost in the merge time, should fix bug
    posted on phoronix in an article. (Note this isn't how you report

    Dave, I can confirm that the patch atop Linus' tree as of this evening (10 March) fixes my E-350 setup. Acceleration appears to be working fine with KMS and Gallium3D. Thanks.

    P.S. I am sorry that you may not like some of my unconventional bug reporting techniques etc, but we all share a common goal -- and that is to improve Linux hardware support. We may just have different approaches to doing so, but this method at least gets the job done (I see that bug #34137 was open for one month with no responses at all) and concurrently allows me to finance my time and hardware expenses.

    Seems to me you could do both : write an article **AND** a bug report.

    But it's hard to write such a sensationalist story if you do

    my main issue isn't with the article, but with the not filing a bug upstream so I can ask for more info and have logs that aren't a pastebin.

    drm.debug=15 runs would have been useful.

    It was only by luck I was tracking down another bug in page flip today and saw the problem in passing.

    Dealing with bug reports tends to be tedious and chews up a lot of time... I did let Alex and John know though a day in advance via email soon as I discovered the issue.
