Has anyone got an Exabyte 8mm tape drive working under -current?  I've 
got one that panics as soon as the driver tries to execute 
st_mode_select(). 

I'm guessing that there's some special quirkdata that needs to be set for 
this beast, (the Exabyte section of quirkdata in st.c is disabled by an 
#if 0 ... #endif) but I don't know the details.

Also, can anyone enlighten me on the differences between rst0, erst0, 
nrst0, and enrst0?  Thanks.
