Update of /cvsroot/src/sys/arch/i386/i386
In directory netbsd1:/local/NetBSD/src/sys/arch/i386/i386

Modified Files:
	mainbus.c 
Log Message:
Add a workaround for buggy i486 PCI chipsets that have trouble with
memory-mapped device access (manifested by an apparent wedging of the
PCI bus):
- If cpu_class == CPUCLASS_486, disable memory-mapped PCI device access,
  leaving only i/o-mapped access enabled.
- Provide a patchable kernel variable (i486_pci_mem_enabled) and a kernel
  option (I486_PCI_MEM_ENABLED) to re-enable it.
