Finally I've find out. The problem is kvm source of package
linux-source-2.6.26 does not include the kvm-66-fix-k7-msr2.patch.
kvm source in package kvm-source 72+dfsg-5 seems to be more up to date;
it includes the k7 patch and more, it seems. Look diffs in the
attachment.
I do not know if this is an error on is intended to be this way.
Anyway, rebuilding kvm modules from source packages solve the problem.
Now long term support kernel 2.6.18 boots fine.
