I have "solved" this problem, and since it drew some interest I'll summarize
what I finally did, at the same time pointing out a small "gotcha" which made
things a bit unpleasant. What follows is for a SuSE 7.1 distro, and will
probably be a bit different for others.
1. SuSE uses a script in /etc called boot for once-off stuff like module
installation. At a certain point it does a depmod -a which effectively clobbers
what was there from the last session. That is why my my previous modprobe
settings "dissappeared". (Gotcha!) A depmod update (depmod -A) would have been
nicer. Does anyone know why update is not used? What does Mandrake, RH do?
2. Somewhere before the depmod, i added insmod -q ide-scsi and insmod -q osst -
and lo and behold, everything worked fine! (You can see an ide-scsi subdirectory
under /proc/scsi, and the scsi file contains an entry for the osst device Of
course, mt /dev/osst status worked as expected.)
3. I still have the append hdc=ide-scsi in lilo.conf. It presumably tells
ide-scsi which ide device to map.
This all strikes me as nasty kludge; there has to be a way to do it through
modules.conf.
