I recently installed sarge on a p75 laptop with ~ 16M of memory. It
was all ugly. Debian used to be so good at minimal installs :-(.

I'm assuming it's printing out more than that, but is going to be
a pain to type out.

Check to see that the kernel is detecting the IDE drive geometries the 
same on both machines (if the boot is getting that far). This is
the IDE messages from a working 2.6 kernel booting on Adrian's wizard:

	Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
	ide: Assuming 33MHz system bus speed for PIO modes; override with
	idebus=xx
	CS5530: IDE controller at PCI slot 0000:00:12.2
	CS5530: chipset revision 0
	CS5530: not 100% native mode: will probe irqs later
	PCI: Setting latency timer of device 0000:00:12.0 to 64

 	/dev/ide/host0/bus0/target0/lun0: p1 p2 p3

Also see if it's running out of room creating ramdisks if it's using
initrd.

If that all looks right, try booting with init=/bin/sh or something to
see if you can get a shell and look around to see if everything looks
as it should.

It's probably going to be a good idea to compile a custom kernel anyhow.
I still have the .deb around for a (possibly insecure) 2.6.8 wizard
kernel if it would help.

HTH,
