Does your Linux kernel have scsi support?  (sounds like it does, but
that was one of the problems I had with a ttylinux kernel in a domU). 
I have also had to mount the Linux image with -t ext2fs in NetBSD
dom0, and modify things in the image, like /etc/fstab.

I think we're spoilt in NetBSD-land with our combined SCSI/ATAPI layer
(thanks, Manuel), but being able to mount an ext3fs as an ext2fs is
one nice thing that the Linux people did.
