Is the self-select PIN available for those who are eligible to file 1040 this year but filed 1040NR last year?

Last year I filed 1040NR-EZ and this year I am supposed to file 1040-EZ. I know my Adjust Gross Income (AGI). I am using Turbo Tax and I am not finding an option for 1040NR from last year as an option.

A document on the IRS website seems to say that I cannot use the PIN this year, but it is ambiguous:
http://www.irs.gov/pub/irs-pdf/p3452.pdf (pdf file, search for 1040-NR and it will take you the statement.)

But on the Turbo Tax website they say and I quote:
"Taxpayers who filed 1040NR for tax year 2006, who are eligible to file Form 1040 in tax year 2007"

Refund Information - TurboTax Customer Care & Support (http://turbotax.intuit.com/support/kb/tax-content/tax-help/efile/4027.html)

Can someone tell me what the facts are regarding this? Or should I file a paper return?

Thanks in advance.

If you use the self-select PIN option, you must know what your AGI from 2006 was, as well as your date of birth.
