btw, we're also working on making some parts of the kernel more robust
against certain types of bugs; for example the ioremap checks and sysfs
resource checks. There's a set of checks and API changes we can do to
make it less likely that drivers end up doing bad stuff; but that's
obviously more for 2.6.28 than for .27
