Is it possible to do identity insert/update in SubSonic 2.0

Question

Unfortunately I'm stuck using this basically undocumented/obsolete library (SubSonic 2.0). I'm trying to do a simple identity insert but I can't seem to get it to work.

Here's the psuedo-code version of what I'm trying to do:

SubSonicExampleObject o = new Select()
                          .From(SubSonicExampleObject.Schema)
                          .Where(SubSonicExampleObject.IdColumn)
                          .IsEqualTo(124124)
                          .ExecuteSingle<SubSonicExampleObject>();

if(o == null)
{
    o = new SubSonicExampleObject();
    o.Id = 124124;
    o.Save();
}

I've also tried adding this code above and below this statement, to no success:

new InlineQuery()
    .Execute("SET IDENTITY_INSERT " + SubSonicExampleObject.Schema + " ON");

    [CODE ABOVE]

new InlineQuery()
    .Execute("SET IDENTITY_INSERT " + SubSonicExampleObject.Schema + " OFF");

Regardless of what I do, SubSonic seems to be ignoring the ID value, and setting it based on the next identity value.

If anyone knows how to do this, I'd be super duper happy!
