Can't speak to the specifics of this, but you want to be very careful not to use kernel modules with PAE: modules are currently without the context of the kernel configuration file, and PAE introduces possible binary incompatibility with modules that dig into VM (which many drivers do). The only supported configuration is to not use modules, but link the driver directly into the kernel when running PAE. This is why the PAE kernel has no_modules defined in the sample PAE configuration file. Various conversations have happened regarding how to address this problem, and I'm not sure we've come up with the right answer yet. There seem to be two conflicting directions: build modules in the context of a kernel module (and get conditionally compiled type/structure/code/... pieces), and try to make the module build entirely independent of a kernel configuration. As someone who uses conditionally compiled components in modules, I tend to fall into the first camp, and no doubt we'll figure out the right answer in due course. The above crash sounds unfortunate too, but quite possibly a separate failure mode :-).
