Just to point out the obvious:

Even though 128MB is the larges value for a single swap partition
in 2.0, nothing stops you from defining and using *multiple* swap
partitions.

With memory prices these days, many folks just avoid swapping and
paging all if possible.  I've never run Linux with a gig of RAM, but
"heavy iron" Sun/SGI/HP servers with 1, 2, or even 4 GB of RAM
aren't that uncommon (esp. by semiconductor PD types running big
place and route or design verification jobs).

For my home workstation, I've got 80 MB of RAM and a single ~100MB
swap partition.  I do start paging sometimes (usually when
netscape gets carried away) and it is *very* noticeable when I do,
but usually things are pretty zippy (even with an old slow
processor).  My work machine has only 32 MB and it's performance
basically sucks (despite the faster CPU).

The answer to most performance slowdowns is usually "you need more
RAM".
