Some TI card readers are supported, and some are not.  And to make 
matters more confusing, its not the model that matters, but how the 
controller is wired in to the laptop and how BIOS configures it.  
Basically, TI has two modes -- one mode is standard compliant and works 
with the driver, the other is proprietary and does not.

The node you list below is *not* the standard compliant node, and will 
not work with sdhost.  We need to write a completely separate driver for 
this part, and I've not had the chance to get to it yet.  (Its further 
confounded by the fact that the only info I've been able to get on this 
part is by reverse engineering some Linux sources... TI has not been 
willing to provide any docs on this part, as yet.)
