So IEEE1284 support is also built into those modules.

I used these same .config settings except with PARPORT_PC_PCMCIA not set
and the IEEE1284 code is compiled into the parport.o module file.
And it's not just the stubs for "IEEE1284 not supported in this kernel".

Are you sure that you have loaded the correct parport*.o modules?
If so, please post more of your kernel log file, showing the surrounding
messages as well.
