Aaaarrgghhh.  I have no hair left, I've pulled it all out.  Knoppix v3.1 is not as good for me as 
v3.3.  I was unable to mount my USB memstick with the desktop icon or from the cmd line.  Said it 
was an invalid block device.  I used the -t vfat option thusly:  "mount -t vfat /dev/sda1 /mnt/pen" 
and I added the sudo to the beginning of the line, which you must do in Knoppix to issue root only 
commands.  e.g. "sudo mount -t vfat /dev/sda1 /mnt/pen" will run the command as root.

Luckily I had the forethought to copy the wireless driver source file to the ISO after removing 
some non-EN docs and html files.   So I used the desktop icon to mount the cdrom and copied the 
extracted files to the /home/knoppix dir, which really exists in the ramdrive, ran make, then 
mounted the HDD as rw, copied the .o files to a new dir on that partition.  Unmounted everything 
and exited.  Now once back into XP I can copy the files to the USB device.

Tonight I'll test the driver on the laptop in the other two distros.  This better work.
