Problems with 2.6.18 - if I remember right:

- dsp system was different
   - problems with sound and related programs
   - the biggest problem
- some user space programs needed more patching than with older
- problems with initfs: bme & cal-tool didn't work properly
- more problems that didn't come out
   - time to get everything work

But yes. 2.6.18 is possible to get work. but there is needed some 
dsp+kernel guru to do this. Using 2.6.26 is just faster way to get

There is old archive about for more information:
