Ahh.  My bad.  I was under the impression that the Ultra133 and Ultra133 TX2
were different cards, due to some strange issue between the card and the DVD-ROM 
drive that I first plugged into it(this drive does ata/66 on the builtin VIA
controller just fine):

pciide1 at pci0 dev 11 function 0: Promise Ultra133/ATA Bus Master IDE Accelerator (rev. 0x02)
pciide1: bus-master DMA support present
pciide1: primary channel configured to native-PCI mode
pciide1: using irq 10 for native-PCI interrupt

--snip--

pciide1: secondary channel configured to native-PCI mode
atapibus0 at pciide1 channel 1: 2 targets
cd0 at atapibus0 drive 0: <Pioneer DVD-ROM ATAPIModel DVD-106S 012, , E1.22> type 5 cdrom removable
cd0: 32-bit data port
cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 4 (Ultra/66)
cd0(pciide1:1:0): using PIO mode 4, Ultra-DMA mode 4 (Ultra/66) (using DMA data transfers)

But then I plugged in the machine's main disk, and it seems to be doing ata/66(all the
drive supports) just fine. :|
Ooops.

Thanks for the replies!
