i have a mitsumi fx-001 (0001?) double
speed drive with what is marked as a
"mitsumi proprietary interface".  

i keep it set on port 0x300, which was
rejected by devsbcd.  turns out that 
just adding 0x300 to the list of acceptable
ports in devsbcd.c is enough to get things
working for me.  those of you with mitsumi
cd drives on nonstandard ports on non-sound
blaster cards might want to try that.

i added it to the updated devsbcd which i got
after applying /plan9/update/9/pc/824494421.rc
from plan9.bell-labs.com.

(you have to do the appropriate magic in 
plan9.ini too, but that's easy.)
