    Hi,

    I'm not sure whether these are going in through some other channel,
    but I notice neither the Alan's hvcs.c or icom.c patches are in
    2.6.13-mm3. In addition, hvc_console.c needs yet another...

    I do have one, but have been gone for awhile. But am willing and
    eager to test (and get it working again :)

    thanks,
