I am running the 2.6.5-8.5 kernel on SuSE 9.0. I initially had problems with 
2.6 kernels because I had not installed and had not 
run /sbin/generate-modprobe.conf
It looks like I now have this sorted out.

leopardi@linfinit:~> rpm -q kernel-default
kernel-default-2.6.5-8.5
leopardi@linfinit:~> rpm -q module-init-tools
module-init-tools-3.0_pre9-2

I have also been using the NVIDIA GeForce drivers for the 2.6 kernel, from 
www.minion.de

Outstanding problems and niggles:
1) Grabdisplay does not work in bttv, so zapping does not work and kdetv 
segfaults. http://bugs.kde.org/show_bug.cgi?id=80141

2) Init scripts and hotplug for 9.0 were not written with 2.6 kernel in mind. 
I believe they have been updated for 9.1. 
See suse.de/people/zoz/sysconfig and suse.de/people/zoz/hotplug

I tried an earlier updated version of hotplug (from the kraxel directory), had 
trouble booting, and fell back to:
leopardi@linfinit:~> rpm -q hotplug
hotplug-2002_08_26-90
I have not tried the new sysconfig, as I suspect this may only work properly 
for 9.1. I am still at:
leopardi@linfinit:~> rpm -q sysconfig
sysconfig-0.23.30-39

3) My use of 2.6 kernel has apparently not made my system completely stable.

4) I have two ethernet ports. At one point when I switched from 2.4 to 2.6, 
the ethernet ports swapped (eth0 became eth1 and vice versa). This does not 
happen now.

5) I had to be careful to keep a copy of the /boot directory and the 2.4 
kernel RPMs, and to update menu.lst so that I could switch between 2.4 and 
2.6 kernels.

6) When I switch between 2.4 and 2.6, I need to remember to use the "nv" 
driver in X11 rather than the "nvidia" driver. The nvidia installer seems to 
be using the current running kernel to figure out what to do, and it 
de-installs its previous installation. So I haven't been able to switch 
between 2.4 and 2.6 with the appropriate nvidia drivers installed in both.

7) Ideally, I would be beta testing 9.1 rather than just downloading stuff 
from suse.de/people. With my current combination of hardware I seem to be 
seeing problems that many others are not seeing. If I could look at these 
problems in a more disciplined manner and report on them through formal 
channels, I might be closer to helping diagnose and solve them.
