No output from SMC1 console with the 2.6.26 kernel (PQ2FADS based board)

No, it's not working for me :(

My pins is configured by u-boot so I disable init_ioports() function
call. Moreover the udbg0 console forks fine... I have no output at all
after "udbg_putc = NULL" line in the cpm_uart driver. As I see it the
cpm_uart driver doesn't run properly after udbg console has turned
