What about using multiple calls to egrep() ?

if(egrep(pattern:"^Widget 5000", string:banner) &&
egrep(pattern:"^Version .*", string:banner) &&
egrep(pattern:"^Bla bla.*", string:banner))do_stuff();

It will match on a banner set on a reverse order, but this should do.

If your banner is static, you may also simply use the "><" operator:

if(device_banner >< banner)do_stuff();
