Heh. I think you mean s/fixed/worked around/.

The bugme tracking this, 3927, is a joyous muddle of patches, 
patches to patches, workarounds, and dueling command line options. 
I ported this patch,
http://www.ussg.iu.edu/hypermail/linux/kernel/0504.0/1625.html,
to 2.6.16-rc1 to fix my pain, but 1) it didn't work without the
disable_timer_pin_1 kernel option and, 2) I don't think it's a fix 
so much as a workaround.
