The difference is that they are not using Thinkpads. Thinkpads are different
in some ways to other types of computers.

The append="mem=XXX" is the solution as other people have said. If you tell
it 128M then your machine is unlikely to boot as the Thinkpad hardware likes
to use the last few hundred K of RAM for shadow or something. Tell it 127M
or watch the boot messages from the BIOS which will tell you how many K of
memory to use.

PS I'm currently on my second Thinkpad and plan to buy a new one in early
2001. In spite of the things that IBM has got wrong their still the best
laptops on the market.
