3.40 oea Getting back into the hombrew game

I've been out of the hombrew scene since the first release of Dark_Alex's 3.40oea firmware. Im finna get my new battery for my PSP in a few weeks (already ordered on ebay). My question is about memory stick compatability. I remember a few ppl were having trouble with the 8gb sticks when they first came out due to the fact that the custom firmware, because it used 1.50 firmware, wasn't able to handle more than 4gb and the stick wouldn't show anything after the initial 4gb. My question is whether or not this issue has been resolved in the newer cfw releases. I have a 2gb right now but...I NEED MORE!! Lol. Once i get errthing sorted out ill get down 2 making my magic stick and pandora battery. Any knowledge on any of these subjects would be appreciated (especially my initial question.)
