Its been long since the hardware issue has been fixed.
This patch uses GPTIMER 1 for all newer board revisions
incl. Beagleboard XM.

  * Browsing through the code, it appears that similar
    change could be applied for these boards:
     - devkit8000
     - omap3stalker
     - omap3touchbook
    However, I don't have access to any of these;
    or information on their revisions.
    I can update this patch based on confirmations.

You might want to send an E-mail to the people who are listed as authors 
in git for these boards.  Otherwise they will probably miss it in the 
onslaught of mailing list traffic.  Unless the PCB designs are based on 
A or B revisions of the BeagleBoard, it should be safe for them to switch 
to GPTIMER1.
