2.4.19-pre7: undefined reference to `ahc_acquire_seeprom'

Hi all,
When compiling 2.4.19-pre7 I am getting undefined reference to ahc_acquire_seeprom' and ahc_release_seeprom' errors on linking vmlinux:

This is a kernel for a 486 _without_ PCI. If I enable PCI support it compiles fine.

Any hints?
