Hmm... I was compiling usb-uhci and uhci directly into the kernel,
then visor.o as a module.

In any case, I can't load any modules under ac14. None. I get
complaints about unmatched symbols. Really fun when /home is on a fs
compiled as a module...

ac13 + crypto works with usb-uhci, usb-serial, and visor as modules.
No problems.

I've gone back and (re)tested with kernels 2.4.1, 2.4.2, ac[36],
ac1[01234]. I can only get a crash on ac12 and ac13. 2.4.2 is broken
after all, and everything after it. 2.4.2 and the ac kernels seem to
fail on 'pilot-xfer /dev/usb/tts/1 -m scsi.pdb' (to install a zTXT
into gutenpalm, doesn't matter what I'm sending), and things seem to
go slower and have more problems as the versions increase. Then I can
crash the system under ac12 and 13. This is using uhci compiled
directly into kernel, with usb-serial and visor as modules.

If uhci + visor is unsupported, might I suggest the following change
to Configure.help to warn people?
