This updates the class code in the device-tree, but sysfs still shows
the old value.

Is this a readonly register by any chance?
Appending a 'viaide->class &= ~0x5;' changes the code paths in
do_ide_setup_pci_device(), now IDE prints 'not 100%% native mode,
will probe irqs later'. Where are the irqs supposed to come from?
