If nobody cares about PNX4008 and nobody tested if it actually works in
the OHCI mode I don't see the point in keeping it around especially if
there are rumors to remove the arch.

It would be nice, if you could manage to compile this thingy without
I2C. In the end one could attach something different than isp1301, no?
So I think, in the perfect world you would probe for your phy and
notice that it is not there and print a message: "Dude! Select isp1301
for OHCI, aight?!"
