It drops into the debugger with "sdopen: no slices" error if I try
to do a mount with no disk or immediatelly after changing disks..
(BTW: I'm running 2.1-stable ! 2.2 floppy does not boot in my machine.)

Well, I looked for it in scsiconf.c, and used this patch:
( BTW: What's an "options NEW_SCSICONF" ? :^) )

Note that ZEUS is my machine's name, and so the define above is true.
(I checked this with grep -l ZIP /sys/compile/ZEUS/*)
No luck. It still boots likes this:
(disk in drive, options SCSIDEBUG, SCSI_REPORT_GEOMETRY, device od0, etc.)
