Would it be harder/easier better/worse to use Linux device drivers
from hOp/House as opposed to writing new disk I/O stuff in Haskell?

I don't think I said anything controversial. I guess I was just
over-simplifying things by only considering PC IDE hardware - but then again
that must get you running on 90% of the systems people are likely to have
lying around to play with a developmental OS on.
On the other hand the average network driver seems to be about 2,000 lines of
code, whereas if you add all the parts of the generic ide driver together you
get about 20,000 lines of code. I guess that answers my question - storage is
an order of magnitude harder than networking, even before including SCSI.

Keean, you should be aware that Lennart is something of a device driver
guru. He knows what he's talking about :-) Go grep for Augustsson in
the NetBSD kernel sometime.
