You had to have hints because your non-ACPI kernel was using IRQ 7 (wrong) for ppc0 rather than IRQ 5. Are you sure your /boot/device.hints was empty? Anyways, once you moved the LPT IRQ to 7, did the PCI IRQs change such that re0 is on 5 now instead of 7? > It's another story on another machine I havem where ACPI is working > much better of 6.0-RELEASE than it had been under 5.4-RELEASE: a Compaq > R3120US.
