vanishing floppy on Tsunami machines

[Michal Jaegermann <michal ellpspace math ualberta ca>]

At the very end of the last year Soohoon Lee posted a fix for
a "vanishing floppy" which is not always recognized by Linux
and he asked for comments.  I did not see comments from anybody
but this "magical write" seems to work for me.  At least nothing
crashed on a machine which showed up the problem it looks like that
it helps.  I have no idea at this moment if this will not mess up
on some other platform.

Once again - any comments from somebody who really knows what this
is doing?  Just in case, here is this patch once again.

A not very convenient workaround does exist.  If before booting
one will access a floppy in SRM in any way then there are no problems
with a floppy recognition in Linux; so booting from a floppy will do
but you do not have to go to such extremes. :-)
