FC6-latest running on a Latitude D610, SATA hard disk; 2.6.19 is okay, kernel built with oldconfig from the known-working setup fails to boot not recognizing the root partition, which is due to ata_piix not loading due to a PCI I/O reserve error. Happens both with and without CONFIG_SYSFS_DEPRECATED (I first had it to N then thought it might have had something to do with the boot error so I rebuilt with Y - no change).
