where does the first boot pause when calcluating the ssh keys?

I've been playing around with trying to get 3.3 installed on my performa
550, and it gets to this point and stops:

    root on sd1a swap on sd1b
    WARNING: / was not properly unmounted
    PRAM time does not appear to have been read correctly.
    PRAM: 0x83da4f80, macos_boottime 0x3ed5b153

(Copied out by hand. If that's not enough information, I can try
using my performa 630 as a dumb terminal and capturing the boot log over
the weekend.)

Although there is no further output, it does echo keypresses to the
screen.

I left it that way for an hour and a half this morning before I had to
cut the power, get the box out of the kids' way, and come to work, but
there was no sign of disk activity, and no further output.

So, I'm wondering, is this where the box is supposed to be calculating
the keys for ssh, or am I looking at what happens when you try to
install in a box w/out FPU, or is this likely to be the SCSI driver
issue, or am I looking at something else?
