Mine works, under kernels v2.2.x.

I have the following in /etc/modutiles/aliases:
alias parport_lowlevel parport_pc

and the (tightly-edited) output of lsmod is:
Module                  Size  Used by
parport_pc              5484   1  (autoclean)
lp                      4840   0  (unused)
parport                 6612   1  [parport_pc lp]

The way parallel port modules are organised has changed with kernels
2.2.x away from a monolithic, PC-specific module to allow for a more
uniform approach to dealing with non-PC and non-standard parallel ports.
That's why I have the alias, to associate the generic hardware-level 
driver name with the particular driver required for the PC parallel 

If you edit files in /etc/modutils, run update-modules as root to ensure
that your changes take effect.
