If you're willing to do that work with the existing driver,
more power to you!  One issue with it is its "old school"
use of "usb_bus" instead of "usb_hcd" ... which means
that it's going to have trouble with some of the trickier
USB device handling requirements, and bitrot.  Though
if you're looking for Yet Another Challenge, merging
those two models -- bus/hcd -- needs to happen... ;)

I had some misgivings about teaching the OHCI code
to act that way, but haven't had a chance to look at
the code in any detail.  I was pleased to have seen two
reports of success using it (you did try the "current
working version" yes?), given the otherwise unusable
state of the current SL811 code.

In any case, there are other OHCI chip support patches
ahead of that in the queue, like the pxa27x support and
the big-endian OHCI patch (for some PPCs).  That SL811
OHCI-emulation couldn't merge for some time; I think
Lothar agreed it needed cleanup.  (So I just now
forwarded your comments to him!)
