This is fixed, was caused by PCMCIA. Fix for that is in Eric's -fix or -devel 
branch already.

Yea ... PCMCIA problem as well.

Segfaults were caused by pcmcia too I think. But the regulator driver is already 
in regulator tree.

Yea, I know this patch is kind of big and beefy ... I've been busy as well, 
that's why this patch is such a crap, but really, we kind of need this in. I 
believe after we have these two (zaurus-rework) patches in, things will be a 
little calmer for a while.

That is, until someone starts digging around sharpsl-pm and spitz-pm, which 
seriously is totally terrible code. The horror it gave me was worse than talking 
to tired Russell ;-)
