What are these features?

External RT patch that only supports PPC arch atm.
Also I've encountered some stability issues with PowerPC branch
(card hangs after some time for undetermined reason).

Do you get an oops on the hang?  would be useful to know if we have  
an issue in arch/powerpc

If you are forward porting the Freescale patches and not using the in
kernel driver that would explain the issue.  There are bugs in the
Freescale driver that have been fixed in the driver that is in the
kernel.

I only ported what needs to be i.e. the platform initialization part.
I'm using the regular USB drivers (EHCI-FSL) from vanilla 2.6.19,  
this part
hasn't be ported from old 2.6.13 BSP code (which would have been  
useless).

The goal of the patch i've sent early is to init the USB bus the  
same way
it is done by OF device tree in arch/powerpc/sysdev/fsl_soc.c (but  
for PPC).

Does it sounds ok to you ?

that sounds reasonable.

Take a look at this patch from Randy Vinson that adds support to arch/ 
ppc for USB.
