A short summary is that memory barriers are needed in several places for correct operation on my MIPS based platform.
It'd be good if you could find out whether the latest 2.6 is missing any of these. It's got a bunch of wmb() calls already, in ohci-q.c ...
As you know ohci-q.c is quite a bit different than usb-ohci.c from 2.4.29, but It looks like it could be OK in this respect. However I don't have the 2.6 kernel ported to my hardware so I cannot test it.
