X doesn't crash - I mustn't have made that clear. I boot to a console, and the
login screen vanishes from the console before I can log in. The three fingered
salute returns a visible console, and starts a shutdown. I can get in with the
new system, or rescue disks, but can't find anything :-(

I thought it was giving up on the  drive :-/. Could it be a chipset problem?
The kernel was built for a '586 - 133 with a bogstandard chipset; I upgraded to
a   K6/2-500 with an Apollo P5MVP3 chipset and never rebuilt. DMA is enabled by
default, and SHOULD work.

I took HDPARM out of  /etc/sysconfig/system in my old system (Thanks Bill) and
booted it. I got to the login promp (Hurray), and then the screen vanished as
before (Boo). At least it got past hard drive optimization. That must be a
malfunction of the Seagate drive. I took out my old motherboard because the two
hard drives would vanish periodically, usually under load in linux (ON THAT
SAME SEAGATE DRIVE). I needed an upgrade anyhow.

Now the only thing I have to figure out is why on earth the old system dies
after a second whether I log in or not. Saying "No" to everything in the
Interactive startup still produces exactly the same symptoms; All 6 consoles
go blank, and about once per second there is a little hd activity, accompanied
by a glimmer of something onscreen. No shapes, just a flash. I have tried with the 2 
old kernels
(2.2.13-7 &  2.2.14-15) with nothing in the interactive startup going, and one
second after that system shows me a login console, it's gone :-(
