I'm a bit confused here. Do you mean that the warning message is not printed or that disk is not limited to UDMA33? Could you send "hdb" part of 2.6.17 dmesg? > The disk in question is ATA66 capable Please send output of "hdparm --Istdout /dev/hdb" command. This is probably one of the early ATA66 disks with the buggy device side cable detection. CONFIG_IDEDMA_IVB=y should help but I'm currently working on adding automatic detection of such disks.
