The processor itself can support OTG.

Am I being told that if the kernel was working perfectly I could still 
not use a program such as 
http://maemo.org/downloads/product/OS2008/usbcontrol/ to manually switch?

I have heard a rumor that perhaps USB is not well enough supported yet 
in the kernel for OMAP3, though very unfortunately I have not taken time 
to look at it.

If I could never ever use the n900 as a host that's absolutely terrible 
and extremely disappointing from a development viewpoint.  It is no 
better than other phones then for many possible applications.
