I've installed trunk r35847 in my wr307n v1.7. The kernel is 3.7.9 which doesn't supports sdparm module (it requires 3.8.2) so I can't set up 3g. I've already bricked the unit trying sysupgrade (manage to recover through serial port though). Would it be safe upgrading the kernel w/o upgrade the trunk? or any way to setup 3g in a v1.7 unit?

it's for writing howtos not asking 
you've already unbricked your board so have no worries! yed and you can build your custom image by following these :

ufff! just browsing the procedures you linked scares me more than the serial unbrick I had to perform which is not so difficult if you get a serial-usb adapter (1.3€ at ebay shipping included. Awesome).
I'm thinking to wait for a better openwrt support to v1.7 units while there is not a simple solution.
Thanks for you answer.
