That would normally be what I would do, and it may yet happen. Problem is, I don't have a 64-bit system with enough disk space to do the kernel builds with a cross-compiler, and local (native) builds on the PWS are taking 36+ hours each these days. Unless I get *really* lucky with the bisects, the task will take a couple of weeks. Anyway, I've whined enough :-). Might as well get started... --Bob
