As far as your question, I can confirm that the rooting of my v905r on the stock rogers 3.0.1 romworked flawlessly.
But a warning to all rogers v905r owners. I upgraded my rogers v905r to 3.1 using the files and method from the google code project page. The rom is for tmobile, and it clearly states that optimus pad owners flash at their own risk, but i tried it anyway. Everything else worked fine, but I noticed that i was only getting an E (edge) connection instead of a high speed hsdpa one. After checking my mobile network and apn settings I did a little research and as far as I can tell the problem is that rogers and t-mobile use different frequencies for their high speed networks. I have found a hidden menu that lets you select different frequencies, but even selecting the proper one has no effect. I also had a backup of my original rogers 3.0.1 system partition, and was able to flash back to that once the downgrade tool was available (thanks again to the handful of amazing developers working on this device) but this STILL didn't fix my problem.
I'm not a dev by any stretch of the imagination, but my theory is that there may be a radio partition where that kind of thing is stored, that got overwritten during the upgrade, and since I only have a backup of my system partition, can't be restored.
So, yes you CAN upgrade without bricking your device, but unless I'm missing something you'll lose your 3g connection (and it seems to have made my gps wonky too). If you're a risk taker, I would definately back up ALL partitions before trying anything.
