The 2.6 kernels have PCI quirks related to the M7101, which might explain
why you didn't have to care about the address there. This might mean we
could even get rid of the force_addr parameter in 2.6.

Why don't you pick the exact same address in 2.4 that was automatically
detected in 2.6? I'd assume this would be the safest choice. Or, like
Mark said, just any free address (i.e. from a range not listed as used
in /proc/ioport) should do.

Thanks,
