I just narrowed the problem to an interaction with the tpctl tools.
If I turn off /etc/init.d/tpctl (turn its sysV symlinks into K* links), I get no DMA errors. I can then reproduce the errors by /etc/init.d/tpctl start (which runs tpctl and loads the smapi and thinkpad modules), as long as I am in runlevel 2 or higher. If I'm in runlevel 1, I get no errors.
I'm using Debian's tpctl package (4.17-1). With kernel 2.6.13-rc3, I'm using the thinkpad modules from Debian's thinkpad-source (5.8-4) package. With 2.6.11.4 I use the 5.8-3 package for the source, but it's almost the same as 5.8-4.
