Did anyone have luck with ramzswap included in kp49? I get instant reboot every time.

It never crashes for me, are you using power of 2 sizes for disksize_kb?
EDIT: I should add that I use my own kernel build, but it is currently derived from kp49 and parts of bfs. I can make it available if anyone so wants.

I had a crash (running KP49) with the following approach:
(I use my sdcard for swap)
So, after a short period of contemplation I went with:
And everything is groovy again. The old N900 is snappier than a crocodile who's found himself at a penguin parade.
Code:
insmod /lib/modules/current/ramzswap.ko disksize_kb=65536 swapon /dev/ramzswap0 swapoff /dev/mmcblk1p2; swapon /dev/mmcblk1p2
So, after a short period of contemplation I went with:
Code:
swapoff /dev/mmcblk1p2 insmod /lib/modules/current/ramzswap.ko disksize_kb=65536 swapon /dev/ramzswap0 swapon /dev/mmcblk1p2

2^16 = 65 536

you are somewhere in between:
2^16.5849625 = 98304

98304 fits in that category (and works fine for me too)
