The define was put in under complete ignorance. At the time of the SCSI 2
specification, there was a reference in it to 'known' density codes. The
limitation set in st.c is bogus in that it ignore all vendor unique codes
(from 0x80..0xff).

I removed this limit from -current as of 7/30/98 but hadn't the energy to
do the pullup requests to get it into 1.3.3. Sorry.
