Hmmm, I was investigating how the init scripts load the sound modules in
fc3 and perhaps one "feature" there is causing your problem. Hardware
related modules are loaded early in /etc/rc.d/rc.sysinit. The shell code
there looks at /etc/modprobe.conf but it also adds modules returned by
/sbin/kmodule (part of initscripts). I don't how it does what it does
(have not tried to look at the code), but it lists types of hardware and
the corresponding kernel modules. I presume this is an attempt to
initialize any hardware that has not been configured. If this is
returning the undesired prism module then that's probably the problem.
Try running it on a terminal (/sbin/kmodule).

Probably a bug in the install program.

That's good to know...
