You are lost if every key leads to the same error.  So you cannot even
do the setkeycodes hint. (Btw.: Does the message read "code 0x11c" or
"code 0x1c"?)

As you can type: linux floppy=thinkpad at the LILO-Prompt, try to add
the following kernel-parameters. They are described in
Documentation/kernel-parameters.txt in the linux-source tree.

	atkbd.reset=	[HW] Reset keyboard during initialization

Maybe this should be set to 1 or left blank.

	atkbd.set=	[HW] Select keyboard code set
			Format: <int> (2 = AT (default), 3 = PS/2)

Try the 3 because the kernel message says: raw set 2, which doesn't work.

Please notice:

Slinky has no hardware-detection at all - it only uses
whatever the LINUX kernel detects.  There are only very few but
common drivers compiled into the booting kernel.  Have a look at
/proc/config.gz of a running Slinky to see how the boot-kernel is

You can safely do a boot with the Slinky boot-floopy on
a "more standardized" computer than your 750P is, open a shell or
switch to the second virtual console <ALT>-<F2> and do:
gzip -dc /proc/config.gz (Scroll back with <SHIFT>-<pgup> or pipe
thru a pager).

If you really need changes to this configuration, you must compile a
new kernel with these settings changed. Then copy this kernel to the
Slinky-development-tree and create a new Slinky-boot-floppy.
