Ah, an explanation finally ;-)

So what's the correct way to boot an XL into Linux ?

This should definitely go into the Alpha install docs.

But potato will use 2.2.14 presumably.

I always thought that we _don't_ want to urge them to produce their own
kernels (the Debian kernels should work in most circumstances).

Why don't we provide a generic-smp boot floppy set. Besides 2.2.14 already
provides a smp kernel package so you got the chance to install it yourself
after the initial installation.

What's the railroad to me ?
I never go to see
Where it ends.
It fills a few hollows,
And makes banks for the swallows, 
It sets the sand a-blowing,
And the blackberries a-growing.
