Iberians incinerated their deceased... so it's very difficult to get DNA from ashes; but luckly they inhumated their babes under their homes as i think did the Anatolian neolithic farmers, so from such cases it would be possible to extract quality DNA... but we might wait yet.
For ancient Iberian mtDNA we have:
Sampietro, M. L., Caramelli, D., Lao, O., Calafell, F.,
Comas, D., Lari, M., Agusti, B., Bertranpetit, J. &
Lalueza-Fox, C. 2005 The genetics of the pre-Roman
Iberian Peninsula: a mtDNA study of ancient Iberians.

Palaeogenetic evidence supports a dual model
of Neolithic spreading into Europe
M. L. Sampietro1, O. Lao2, D. Caramelli3, M. Lari3, R. Pou4,
M. Martı´4, J. Bertranpetit1 and C. Lalueza-Fox
comparable results come to be more or less:
late neolithic - Iberians - medieval Catalonia

but it's to take into account that major differences are found in two articles related to modern Catalan mtDNA...
By the way I would like to know which fraction of such mtDNA might be of indoeuropean origin, because looking at such data seems like the "indoeuropean-R1b-males-that-lost-their-indoeuropean-language-for-Iberian" would be a only-males tribe...
