Is that the generic-24 build?  If so, it doesn't boot on my PowerBook 
145B either.  Or is this a different kernel?

With -24, There's a lot of clabber about every partition on the SCSI 
drives that doesn't happen with the 1.4.2 generic kernel:

"could not mode sense (4/5); using fictitious geometry"

The boot process gets through reading the time from PRAM, notes that
it doesn't seem to be accurate, identifies the root file system type
as ffs, and then

"panic:  cnopen:  cn_tab->cn_dev == NODEV
