The manpage for modprobe mentions that dashes and underscores are
treated interchangeably in module names. The stack trace dumps seem
to print module names with underscores. Use bash to replace _ with
the pattern [-_] so that file names with dashes or underscores can be
found.
For example, this line:
[ 27.919759] hda_widget_sysfs_init+0x2b8/0x3a5 [snd_hda_core]
should find a module named snd-hda-core.ko.

Note: This should apply atop linux-next.
Thanks to Doug for showing me the bash string substitution magic.
