So, lets come back to routing of IRQ. 

As far I understand, I have to use ACPI for providing PCI and IRQ. right? 
AHCI and NIC should use IRQ from ACPI, right? 

	<start name="acpi">
		<resource name="RAM" quantum="12M"/>
		<binary name="acpi_drv"/>
			<service name="PCI"/>
			<service name="IRQ" />
			<service name="PCI"> <any-child /> </service>
			<any-service> <parent/> <any-child /> </any-service>

	<start name="ahci">
		<binary name="ahci" />
		<resource name="RAM" quantum="10M" />
		<provides><service name="Block" /></provides>
			<service name="IRQ"><child name="acpi" /></service>
			<any-service> <parent /> <any-child /></any-service>

	<start name="nic_drv">
		<resource name="RAM" quantum="8M"/>
		<provides><service name="Nic"/></provides>
			<service name="IRQ"><child name="acpi" /></service>
			<any-service> <parent /> <any-child /></any-service>

Should I use «route» section in ACPI? What should I route? PCI?
