Well, it turns out that I don't have a swap partition, not even 1 bit.

Fortunately, I didn't have to go that far.
What happened was that I had installed Kubuntu just before the problem appeared. I had chosen the same swap partition that I had been using for Mandriva for Kubuntu also. During installation, Kubuntu said that /boot, / and swap partitions must be formatted, I said yes, and the installation went fine. Then I booted into Mandriva and the rest you know. Mandriva had fstab entry for swap as
LABEL=SWAP-hdb7 swap swap 0 0. When Kubuntu formatted it, the label was changed to linux-swap. I changed the fstab entry to
/dev/hdb7 swap swap 0 0 and everything is fine now.
I am still wondering, when I did 'top', why I didn't notice the entries next to 'swap' that said '0 total, 0 used & 0 free'. I looked at only the last entry which always say 200-700 MB cached. This might have given me the feeling that swap is there.
A check of /var/log/syslog revealed that kernel had killed kdeinit and kwin because of out of memory, which explains why KDE crashed.
Thank you guys very very much for helping me solve this.
