Hi.

You can use trunk and the following options in your baselayer:

{
    maxResolution: ...,
    minResolution: ...,
    resolutions: [..., ..., ...]
}

If you have resolutions set in the map use these options in the
baselayer instead:

{
    maxResolution: ...,
    minResolution: ...,
    numZoomLevels: null
}

Note  that this behavior is new (hence the need to use trunk) and that
the corresponding ticket [*] has been reopened lately, which means
that things may change again before the 2.10 release.
