Yep. Have done it often.

Dare I say it? The one that starts with an 'L' and ends with 'X' has a
"swapon" and a "swapoff" command. If you try to swapoff when there is a
lot running on the machine it will grind to a screeching halt. At least,
the last time I typed swapoff (foolish me, I was running X and several xterms
on a machine with 6 meg!) it killed the machine dead.

I agree it would be nice. Although I'm sure in a lot of cases, adding swap
generally means totally hosing a disk somewhere to rearrange partitons. So
a kernel rebuild shouldn't be that big of a deal.
