I have an ISA card for the DOC2000, I boot up my workstation, carefully
plug in the isacard, modprobe doc2000, insmod docprobe insmod mtdchar
(if necessary) insmod nftl (if necessary). Do whatever I need to do,
rmmod nftl, rmmod docprobe, rmmod doc2000, and remove the card. On my
machine, doing this using the devfsd nodes causes an oops after the
first time, a simple workaround is using hand made device files.
