This is what I have for kernel 2.6.14.5.  Note, I'm not saying that this
is what *you* should have.

I too have an external USB drive, but I use it purely for backups.  I
have not attempted to boot from USB drive yet.

$ grep SCSI /boot/comet-config.2.6.14.5 | grep -v 'is not set'
# SCSI device support
CONFIG_SCSI=y
CONFIG_SCSI_PROC_FS=y
# SCSI support type (disk, tape, CD-ROM)
# Some SCSI devices (e.g. CD jukebox) support multiple LUNs
# SCSI Transport Attributes
# SCSI low-level drivers
CONFIG_SCSI_QLA2XXX=y
# NOTE: USB_STORAGE enables SCSI, and 'SCSI disk support' may also be
needed; see USB_STORAGE Help for more information

This is what appears in my logs when I switch it on:
