scsi emulation

["Michael P. Soulier" <msoulier@storm.ca>]

    So I'm told I need scsi emulation for my IDE CD writer and xcdroast. So, I
recompile 2.2.18pre21 with scsi support, emulation and scsi cdrom support.
xcdroast still complains. 
    So, I try them as modules instead, and get this

lupus:~# depmod -a
depmod: *** Unresolved symbols in /lib/modules/2.2.18pre21/scsi/scsi_mod.o

    Help?
