suse - kernel downgrade from rescue system!
 

Hello all
I'm having some troubles after the last kernel update.
It happened that after some time I restarted the computer and it didn't load kde. The only thing I could see was a black screen, which didn't allow me do anything.

I managed to have a rescue system with the installation dvd, but from there I don't know how to downgrade the kernel, as I think it didn't save the downloaded upgrade rpms!

Do you know how to solve this problem?
Thanks in advance!
