SPI port via the Audio Code header

Has anyone ever tried to run a SPI device off the Audio Code Header on the iMX 25 PDK Personality board?  I have a chip with an SPI interface, but it has a few quirks.  I need to experiment with the chip first to decide if "so broke" we have to bit-bang it or if the SPI interface on the chip is functional enough to run over SPI.  That seems like the easiest access point to an SPI port, but curious if anyone else has tried it.  Or if there is a better solution I'm not seeing ....

Yes, I have developed iMX25 PDK 3stack SPI driver for Nucleus Plus RTOS and tested it with the pin outs available at audio. jac.
