Write support

[Patrick Higgins]

I've finally gotten everything to compile and boot correctly, but now I
find that write support seems to have some problems.  The first is that I
can't mount the filesystem read-write in the first place--I have to mount
it read-only and then remount it read-write.  I suspect this is
intentional.  However, after remounting read-write, I start getting these
types of messages:

end_request: I/O error, dev 5d:01 (unknown), sector 4
end_request: I/O error, dev 5d:01 (unknown), sector 10
end_request: I/O error, dev 5d:01 (unknown), sector 12
end_request: I/O error, dev 5d:01 (unknown), sector 536


I find that if I create a file, it will show up in ls output until a round
of "end_request: I/O error" messages show up, after which point it will no
longer appear, but I am still able to cat the file correctly.

The driver also detects two Disk on Chips, although I only have one, as
seen in the following console output:

Am I missing anything obvious?
