verbatim, lstlisting in overfull box

Ciao a tutti!!

Devo poter scrivere del codice xml o bash e uso in alcuni casi

`\begin{framed}
\begin{verbatim}
flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow up rep_good pni cx16 lahf_lm \textbf{svm} extapic cr8_legacy
\end{verbatim}
\end{framed}`

oppure

`
\lstset{frameround=fttt}
\begin{lstlisting}[firstnumber=1,numbers=left, numberstyle=\tiny]
