Not yet but I've done it using RTAI, can't be any more difficult with
RTL.

Depends on which DOC driver you want to use and what your final usage
will be.
For in-house work that won't be distributed use the M-Systems driver and
utilities,
compile the driver into the kernel and follow the instructions. We
(LineoISG) have
produced a modular version of the M-Systems driver (for M-Systems) but
I'm not
sure when it's going to be generally available. You can use that without
breaking the
licence for distributing the end-product.
Visit http://www.m-sys.com for more info.
An alternative would be the MTD project which is producing a completely
GPL DOC
driver that you can link into the kernel without any legal issues.
Visit http://www.linux-mtd.infradead.org for more info.
I use SYSLINUX to boot the thing using an INITRD (because I use the
modular driver)
but I've used LILO with the driver in the kernel too. Be aware that
you'll need a patched
version of LILO (and boot.b) which you can get from the MTD site if you
use the MTD driver.
The biggest problems were the floppy-disk shuffle and the 'unexpected'
problems of using
a read-only root filesystem. I partition the root fs into 2 parts, a
main RO partition and a
(small as possible) RW part. Be aware also that the MTD driver is not
yet complete, it
doesn't currently do wear-levelling or error correction (to the best of
my knowledge).
Hope this helps
