Yep, zaurus is currently pretty broken; I don't think charging from
Linux works at all, so I simply power down back to bootloader for
charge.

Anyway, suspend/resume is currently more important for me than charge,
and I'd like to get at least that to work.

Could we apply the trivial patch from "zaurus c3000 aka spitz: fix
resume" , and preferably push it to linus for 2.6.31? One version
where kernel suspends/resumes would be good.
