Nobody's saying loadlin is the problem.  The problem is that some BIOS
chipsets don't allow the kernel to detect more than 64MB of RAM
(Compaqs are famous for this).  When this happens, you need to pass a
boot parameter to the kernel telling it how much RAM you have (or, you
can just run linux with 64MB ... seems a bit of a waste if you've paid
for a bunch of RAM though).

I've owned systems that needed the mem= argument, and systems that
didn't.
