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