Hi Neil,
OHCI and UHCI are different Host Controller designs
so they are not compatible.
UHCI is from Intel and
OHCI from Compaq, National Semiconductor and Microsoft.
But there is a patch
for the usb-ohci driver for the SA-1111 from Brad Parker.
You can find it in the latest 'Nicolas Pitre' patch for
the ARM-Linux patch "diff-2.4.5-rmk6-np1":
Here is the announcement from Nicolas at the
sa1100-linux mailing list:
(http://www.lart.tudelft.nl/list/list.php3?arc=sa1100-linux)

(you also need a linux-2.4.5 kernel and the 2.4.5-rmk6 patch :)
