Are those bits per device?
Because I see the following for a onboard controller:
[...]
ACPI APIC Table: <INTEL  DG33BU  >
[...]
atapci0: <Marvell 88SX6101 UDMA133 controller> port 0x2018-0x201f,0x2024-0x2027,0x2010-0x2017,0x2020-0x2023,0x2000-0x200f mem 0xe0100000-0xe01001ff irq 17 at device 0.0 on pci2
atapci0: [ITHREAD]
ata2: <ATA channel 0> on atapci0
ata2: [ITHREAD]
[...]
ad4: DMA limited to UDMA33, device found non-ATA66 cable
ad4: 117246MB <Maxtor 6Y120L0 YAR41BW0> at ata2-master UDMA33
ad5: 156334MB <Maxtor 6Y160P0 YAR41BW0> at ata2-slave UDMA133
Which is strange, since both drives are on the same cable...
