It doesn't compile, has never compiled, and doesn't look likely to compile
in the near future.  It's a fairly frequent question on the mailing list.
We should stop asking the question on PARISC until someone's written
the code.

That's not true.  Everything anyone could want to know about the Lasi
floppy is in and that
document tells you it interfaces to a "Western Digital WD37C65C Floppy
Disk Controller chip (FDC)."

I don't know where to find documentation on that chip, but wikipedia tells
me, "in 1987 they introduced the WD37C65, a single-chip implementation
of the PC/AT's floppy disk controller circuitry, and the grandfather of
modern super I/O chips"

Then they can reenable the Kconfig option then.
