Didn't seem to change things any, but thanks for the tip - I'll remember it
in the future. I've had pretty good luck reusing old configs, but I
generally let menuconfig load the default configuration and then load my
config over it, which may explain my luck.
I wound up making all the parallel port stuff modules which is
worked. There still seems to be something goofy here, but I'll try some
different compile options on a test box and see what happens so I don't
have to keep rebooting my production box.
Thanks!
