Ok, this might solve problems people were having with the DAC960 and
other RAID controllers during the install.

Then again, it may not.  Brave souls wanted, inquire within.  :)

I made a "driver disk" containing updated modules for the DAC960,
cpqarray, and cciss drivers.  The only changes are the
BLKBSZSET/BLKBSZGET ioctls that Martin added.  This disk is ONLY for
i686 machines, I can make one for [3,5]86 if needed.  Hopefully everyone
is using i686.  :)

Lacking any real documentation about how to create one of these disks, I
just looked at an existing driver disk and tried to copy the format. 
The installer does accept it as a driver disk, but since I don't have
one of these raid controllers, I can't test it further.  I expect that
we may run into problems with module versioning/undefined symbols, but
we'll see.

The image is at http://lager.dyndns.org/raid-dd-i686.img

dd this to a floppy (dd if=raid-dd-i686.img of=/dev/fd0 bs=1440k) and
then type "linux dd" or "text dd" at the installer prompt, inserting the
disk when prompted.

If all goes well, it will use the drivers on this floppy during the
boot, and install them on your system as well.

If all does not go well, hopefully you're no worse off than before.  :)

Let me know how it goes...

Your fanatical yet humble servant,
-Eric
