I don't know of an "official way".
There were a number of postings refering to
arch/i386/kernel/pci-pc.c: pci_fixup_via_northbridge_bug()
and claiming that not clearing bit 5 did make the problem go away.
(IOW: Replace v &= 0x1f; /* clear bits 5, 6, 7 */
by v &= 0x3f; /* clear bits 6, 7 */
and see whether this helps.)
