1. KDE 3.2 performance on your machine will never be excellent. It should work but if productivity is an issue then use a "lightweight" window manager.
2. DMA seems to be turned off. If your disk is accessed via /dev/hda then check the value of using_dma:
# hdparm -v /dev/hda
/dev/hda: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 65535/16/63, sectors = 120103200, start = 0
Performance differences between 8.2 and 9.1 are not very big (on a desktop), just KDE is a bit slower due to "visual enhancements". Huge differences that people report are often due to DMA disk access and similar options ... which are turned on by default in one distribution but not in the other.
The 2.6 kernel is supposed to perform better on machines with many CPUs and where many threads are involved. On a desktop, the response should be more "balanced" but don't expect any significant speedup.

Hi Alexander, I'm not too familiar with hdpram, but in yast the ide dma shows hda and hdb in UltraDMA/33 mode. (suse is on hdb). CD DMA if off. Jim
