It seems odd to me that what kind of disk/driver you use makes any difference to the number of partitions you can have on it - I'd have thought by the time you get to partitioning, you only care that it's a block device. Then again, I guess you can't partition a floppy at all, can you (well, I think you can - I think I tried it once - but the naming doesn't cope, so it's not much use), so maybe that argument is invalid. I'd understand fully if scsi emulation stopped you having more than 15 drives per controller, of course, since that's likely to be an addressing limitation carried over from the scsi bus.
