    I can now confirm that I can boot using SCSI disks (the fact that
    this was possible for a while into IDE was a life-saver here :-)
    a Ruffian (pyxis) Alpha using 2.4.0-test11 kernel and two patches
    posted by Ivan (bridges-2.4.0t11.gz and extra ruffian fixes).

    Here are fragments from 'dmesg':

    Those who posted "me too" could you please test that this is not
    only a fluke on my particular machine?

    Thanks a bunch, Ivan. Also thanks are extended to Gerard Roudier who
    provided a crucial hint in the moment when we appeared to be completly
    stuck. :-)
