    [7.] Environment
    Was running KDE on a machine with 'only' 48M RAM ;)

    [7.1.] Software (add the output of the ver_linux script here)
    up-to-date SuSE 6.1 system with a tailormade 2.2.12 kernel

    [7.2.] Processor information (from /proc/cpuinfo):
    [7.3.] Module information (from /proc/modules):
    [7.4.] SCSI information (from /proc/scsi/scsi)
    I do not have the above information right here, since it is a friends
    machine, but I can get them if needed.
