307#
308# ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so
309# that the PS/2 mouse driver doesn't conflict with the console driver.
310#
311# ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so
312# that multiple devices can share the same IRQ, provided that the
313# hardware supports it (it usually doesn't).
