Nope. Still the same, but they are now on different irqs. I noticed 
however that my drm0 doesn't get set up with acpi interrupt routing 
turned on.

With acpi interrupt routing:
interrupt						total	rate
irq0: clk						31844	248
irq4: sio0						0	0
irq7: ppc0						1	0
irq9: acpi0						0	0
irq10: ral0/rl0/vge0/ehci0				7536	58
irq11: fwohci0/pcm0/rl1/atapci0/uhci0/uhci1/uhci2/uhci3	9982	77
irq14: ata0						37	0
irq15: ata1						0	0
irq19							46	0
irq21							6525	50
irq192: swi_siopoll					0	0
irq195: swi_cambio					0	0
irq196: swi_vm						0	0
irq197: swi_taskq/swi_mp_taskq				0	0
Total							55971	437

Without:
interrupt                                          total       rate
irq0: clk                                         331584        331
