g_NCR5380.c in 2.4.20 has direct support for DTC436 with ISAPNP. Look
at the starting comments - is "Added ISAPNP support for DTC436
adapters" present? If not, you will need to upgrade.

With ISAPNP support you don't need any module parameters.

This driver usually hangs the system when given incorrect port
address.
