Have you already tried using linux 2.2.x? It has improved parport
drivers which also allow sharing the port with other devices. I also
experienced that the static version under kernel 2.0.36 doesn't work
(paride/OnSpec 26/pd), whereas the module works fine. I guess the
modules have been tested more, because they provide more flexibility.

So using the modules would be an alternative, as long as there is no
root device on it. But maybe this can be fixed using initrd.

Have you statically linked the driver to the kernel? See above.

you can give the parameter


at boot time, where 0x is the port address and 1 the protocol number.
