here's a simple patch (against 2.6.17-rc6) that fixes the issue by modifying 
the pram addresses for SMC resources. I'm not completely satisfied, as the 
SMCx_BASE registers configuration is board-specific (must be handled in 
init_ioports as you mentionned in your previous e-mail), which will lead to 
duplicated code.
