From a quick test it works for me too, I have both the MMC and the PMIC
(battery, regulators) attached to spi, this is Motorola A910 phone
(pxa27x). Just FYI I applied the patches to 2.6.34 and tested with this
kernel, without the patches I cannot make mmc_spi work reliably (lots
of I/O errors, due to conflict with the PMIC) with these patches I can
finally use the MMC card.

Thanks a lot,
