parport_serial and serial driver?

Hi,

I use non-modular kernel with parport_serial driver built in (NetMos-based
cards, 2.4.latest-vanilla patched for NetMos PCI IDs). The problem is that
parport_serial is initialized before serial driver and thus both serial
ports on that card are detected as ttyS00. This patch helped me:

When the same kernel has parport_serial as a module, everything works
fine, because serial is already initialized.

BTW - Is there a way to specify the order of initialization (module_init)
of certain drivers? What is the proper solution to my problem?
