I believe this KB gave me the best answer:

http://msdn.microsoft.com/en-us/library/1d04y8ss.aspx

to my own lack of luck, this seems to be available for the .net 4.0 version only (and I'm still stuck at 3.5 SP1).

quoting (bold is mine):

When a control is inside a data-bound control that generates repeated instances of the control, ASP.NET generates UniqueID and ClientID values for each instance of the control. The UniqueID value is generated by combining the naming container's UniqueID value, the control's ID value, and a sequential number. This is the case in controls such as the DataList, Repeater, GridView, and ListView controls.

ASP.NET generates ClientID values in a similar manner when the ClientIDMode property is set to AutoID. This can make it difficult to reference the control in client script, because you typically cannot predict the values of the sequential numbers that are used. If you want to access data-bound controls from client script, you can set the ClientIDMode property to Predictable. This makes it easier to predict what the ClientID values will be.

When you set the ClientIDMode to Predictable, you can also set the ClientIDRowSuffixDataKeys property to the name of a data field that is unique, such as the primary key in a database table. This causes ASP.NET to generate a client ID that will be easier to predict and reference in client script if you can predict data key values.

So, in version 3.5, I'm doing it using hidden fields:

    foreach (RepeaterItem item in rptClientes.Items)
    {
        Panel pnl = (Panel)item.FindControl("divCliente");
        Control c = pnl.FindControl("hdnID");
        if (c is HiddenField)
        {
            if (((HiddenField)c).Value == hdnClienteNome.Value)
                pnl.BackColor = System.Drawing.Color.Beige;
        }
    }
