In any case, I now simplified the driver even more, removing the private
lock and the mutex as well. So I'm really ready to trade those 1.5% loss
on 7 years old HW for a simpler and more maintainable driver, if you are
ok with that. It still needs testing on sparc tho.

I am :-)

I'll post a new spin later today after I've tested suspend/resume again.

Ok.
