Thanks Andreas! But niggle still remains:
boot.c's dmi_ignore_irq0_timer_override is still called BEFORE
early-quirks.c, so still gets this calltrace on the warning:

- WARN(1, KERN_ERR "ati_ixp4x0 quirk not complete.\n");
How can ati_ixp4x0 quirk be "complete" at this stage when ati_bugs()
has not been invoked ?
Your ati_bugs() does not seem to be being invoked for my SMBus - here's
the 'lspci -nnvxxxx' output for it:

Hmm, this is now identifying as "438c", not "4385" -
my SMBus PCI id changed from [EMAIL PROTECTED] from pci_ids.h:
#define PCI_DEVICE_ID_ATI_IXP600_IDE 0x438c
#define PCI_DEVICE_ID_ATI_IXP700_SATA 0x4390
But my system is 100% SATA, so why do I see the "IDE" flavor ?
So, 2nd suggested patch:

BTW, I am going to raise a NEW bug about this USB message flood, which
also appeared going from 2.6.26.x -> 2.6.27 , with a patch that does
"when last event is same as this event, don't emit printk" :
