I'm trying to update to -current, but since 1.5 there's too much breakage to
follow the UPDATING instructions. So I tried installing the latest snapshot
via the install kernel. It doesn't boot my PC164.

It gets all the way through til root filesystem is ffs then stops and
doesn't do anything. ddb doesn't give much in the way of hints, but I don't
know how to drive said beasty.

The -current 1.5T boots my box just fine, using a paired down ALPHA config.

Can anyone either supply me with a new install kernel or tell me how to
craft a new install kernel for the snapshot that will boot a PC164?
