Description of problem:
USB modem is detected and configured at boot in /etc/sysconfig/hwconf,
but kernel module cdc_acm is not loaded, nor is the module listed in
/etc/modprobe.conf.  This causes all downstream uses to fail because
/dev/input/ttyACM0 cannot be opened.


Version-Release number of selected component (if applicable):
kudzu-1.1.62-1

How reproducible:
Always

Steps to Reproduce:
1. During GRUB boot screen, plug in and turn on USB modem.
2. Boot.

    

Actual Results:  kudzu detects and configures modem in
/etc/sysconfig/hwconf, but lists no driver.  kudzu forgets to load
kernel module cdc_acm, so attempts to use modem during current boot
will fail until kernel module cdc_acm is loaded manually.  kudzu
forgets to put cdc_acm in /etc/modprobe.conf, so future boots [during
which kudzu is quiet because /etc/sysconfig/hwconf is already OK] also
fail because cdc_acm is not loaded.

Expected Results:  kudzu detects and configures modem in
/etc/sysconfig/hwconf, and lists cdc_acm as driver.  kudzu causes
kernel module cdc_acm to be loaded.  kudzu lists cdc_acm in
/etc/modprobe.conf so that modem works OK in future boots.
