How do you mean boot it with -p? Like, enter 'linux215sc -p' on the SILO
prompt?

[a few minutes later :)]

Wow, that actually worked! Now I see output, and the kernel said:

Console: colour dummy device 80x25

Console: switching to mono PROM 80x34

And later the true problem:

And then this doesn't go well with the fact that qla2xxx is used to access
the only hard disks in the machine. :/

Let's try 2.6.19.2 that used to work... oh, I seem to have demolished its
initramfs image. Somehow.

I wish I knew the explanation for that -p switch :) I can't find it
documented anywhere...
