My patch works well (i can read from pdc kdb) for serial_1 but for graphics(0), I get well a login prompt from pdc but unfortunately I don't yet reach to read from usb kbd. But does it make sense to have pdc_console when we have an sti console? (imho it have well sense for a serial and lan console. Please advise.) Thanks again, Joel
