My disk too has been forced to use Ultra DMA mode 5,
see http://marc.info/?l=openbsd-misc&m=122235339020243&w=2
Being lazy enough to look at the source then, I only noticed that
the mode is limited from above (I was trying to use mode 7);
your example shows it is also bounded from below.
See the above thread for the answer I was given:
the wd(4) flags are not necesarilly used, e.g. they
are ignored on my pciide (and your too, probably):
(me) pciide1 at pci0 dev 31 function 2 "Intel 82801I SATA" rev 0x02
(you) pciide0 at pci0 dev 31 function 2 "Intel 82801H SATA" rev 0x02
"The flags are used only with controllers that support DMA operations
and mode settings (like some pciide(4) controllers)." - wd(4).
