It's a known issue? For this machine or a general issue?

I'll look more into it; it solved the issue of sysinstall not seeing
the drive, but it may just have been the initial 

`dd if=/dev/zero of=/dev/da0 count=1`

It shows sysinstall creating the parition and running newfs - in fact,
it appears to finish this process.  It is either immediately after or
during this process that it reboots.

On subsequent sysinstall attempts, going to create the labels does
show the partitions; they have just not been specified with mount
points. I am not in front of the machine atm, but will be tomorrow. I
can verify what I say then.
