I saw (and tried) an earlier version of these instructions, basically the 
issue was that I couldn't LOAD a module because said module was already 
in the kernel.  In this case I don't think such a module is so it might 
work better, not 100 percent sure.

Well, I'll have to modify them somewhat -- no floppy support here (lame, I 
know), but perhaps it'll work, I'll give it a try tomorrow.

Thanks for the tip.
