Ok, I could provide other numbers. At work I compared a PIII 450 running 
Slackware 8.1 with a P4 2.2 running Win2k.
The KDE desktop on the slow Slackware box was faster there then the Win2K 
desktop. But you are right that Win XP boots significantly faster.

I guess this depends a lot on the distro (I also have the impression that Suse 
boots especially slow).
You can probably disable some stuff when Suse boots.
have a look at kde/share/Autostart and move away the desktop files you don't 
need, then all these things won't be started when KDE starts (I always create 
a folder "DontAutostart" where I move these files to).
Also have a look whether you need all system services which are started on 
Suse.

Another idea would be to delay some things during booting, so that the display 
manager (KDM) is started and when it is running start the remaining system 
services (httpd, smbd, rpcd, portmapper, ...)

From following this mailing list, I'd say yes.

Bye
