Get the pre-patch-2.1.96-1, it has the new updated aic7xxx drivers which
are thread and SMP -safe. Compiled fine for me, do nothing but a
monolithic mini-kernel, since I (at least) find since kmod doesent do
dependency loading it is non-functional (ie. if you have to pre-load
your modules, why do you need a module loader? Kmod is a really nifty
feature, but it either has to be revamped or modprobe must send the
right signals to it).
