My N900 can boot kernel from v3.12-rc5-n900 branch compiled with 
arch/arm/configs/rx51_defconfig. Also it can boot full Maemo5 
system (with CSSU and some minor system changes) and usb network 
via g_nokia.ko gadget working fine...

So if it does not working for you then kernel usb subsystem could 
have problems with using gadgets directly from zimage.
