PROBLEM: v2.4.29 won't compile with PCI support disabled

["Don Guy" <mostly_harmless@sympatico.ca>]

PROBLEM:

Attempts to compile v2.4.29 with PCI support disabled result in the
following errors:

drivers/char/char.o: In function `siig10x_init_fn':
drivers/char/char.o(.text.init+0x12cd): undefined reference to
`pci_siig10x_fn'
drivers/char/char.o: In function `siig20x_init_fn':
drivers/char/char.o(.text.init+0x12ed): undefined reference to
`pci_siig20x_fn'

It has been suggested that enabling PCI support in the kernel will make this
go away however a) enabling PCI support on a 486 which only has ISA & VLB is
downright silly, and b) a test run with CONFIG_PCI=y resulted in a plethora
of other errors.
