All I notice (via grep) is:

  access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or dir...
  open("/etc/ld.so.preload", O_RDONLY)    = -1 ENOENT (No such file or dir...
  access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or dir...
  access("/lib/modutils/macros", R_OK)    = -1 ENOENT (No such file or dir...
  stat64("/etc/conf.modules", 0xbfffb42c) = -1 ENOENT (No such file or dir...

I've never strace'd modprobe! ;^)  I also haven't had a reason to strace
in a while.  (For the most part, Tux Paint isn't crashing, and it's about
the only Linux development I've had time to do lately.  Getting rusty!)

All I get is:

  depmod: *** Unresolved symbols in /lib/modules/2.4.27-1-686/misc/atarisio.o

"atarisio" is a module I compiled from source, and will need to recompile,
it seems. :)

Hrm...  I see (via strace) that /etc/modules.conf is being read.

It looks like this was generated by 'update-modules', and I see:

  ### update-modules: start processing /etc/modutils/alsa-base

And in there, I see /this/:

  alias sb off


Hrm!  Time to Google again!
