I cannot judge about the "cleanness" because of possible changes of initialization time of pci/pnp or whatever. I can confirm that ACPI resource declarations (especially (only?) in the general motherboard devices) are often rather broken. Therefore I like your general approach compared to the per machine dmi match quirks. I expect the latter (dmi matching) is rather hopeless.
