No I haven't tried 99-pre5. 2.4.0-test is the first kernel I tried on this
machine. Kswapd uses about 86-90% CPU. Then I grabbed ac17, but now kswapd
takes even more CPU.

And believe it or not with 2.4.0-test1 I went through the whole process of
installing something workable on a 32Mb partition, 32 Mb swap space. It
took me a few days ...
