I suspect the basic problem is that, since the on-board display in this

There are some older ATI Mach64 based cards that have had trouble
with some versions of the Linux driver. Perhaps you could tell us
the exact model?
It's not a chipset I've seen before (made by iXMICRO, whoever they
are). But since I'm now in Linux, I can do an lspci -v:

The thing did come with the Mac from Apple as far as I know, but I
know no more about it. There's also this from the kernel boot sequence:

I'm not certain exactly what driver it's using. And the
"unsupported" bit worries me.
So, currently I can access the machine via the serial console or with
SSH. I'm now doing an upgrade to sarge, and then I'll try building
kernels and see what happens. There's still a couple of loose ends (like
finding out why quik doesn't work: I'm still using BootX, and why
networking stops periodically), but we're basically there.
There used to be a bug in quik that made it break on G3 processors. It
was originally written for 601 and 604 based boxes, and most people
started using BootX about the same time that G3 boxes became popular.
I'm pretty sure the patch for G3 support didn't make it into woody.
It probably works in sarge, but I'm not 100% sure on that.
I did get the g3 patch for quik, but it hasn't helped. It may be
that I just have it configured wrong: this is all new stuff to me yet.
