...well, hopefully the NetBSD/alpha installation procedure will see some
improvement soon... esp. now that we can install NetBSD/alpha boot blocks
onto CD-ROMs.

Looks like you've discovered a neat little "feature" in FreeBSD.  They
sort of require that disks have a DOS MBR partition table on the disk
to define the disk's "slices".  You'll probably need to fdisk (or whatever
the FreeBSD equivalent is) the disk to define the MBR... although I 
don't know what NetBSD/alpha is going to think of that :-)

Do you have another system from which to dd the image?  Alternatively,
any FreeBSD folks who might read this know how to work around this lossage?
