Xperia X10 :: Micro SD Expandable Memory?

I have run a variety of custom roms on both phones. One of my favorites was the aosp version 2.2.1 from Wolfbreak, that allowed applications like Abobe Flashplayer 10.3 which is a large application >10 MB; to be moved to the SD card. Now what happened to this very effective button that is now shaded out in the new 2.3.3 firmware? I'm not seeing the "move to SD card" button lit up in any of the custom roms for 2.3. either. Only a few apps I was able to move to the SD, most of them cannot be moved anymore. I think that it is important for the xperia x10, which does not have the amount of on board ram than some of it's cousins like the samsung captivate for example, where the need to run apps from the SD card is basically built in with 16 GB thumb drive that's buried, and an additional expandable memory slot for users to install any size up to 32 GB micro sdhc chip, which brings up my second half of a question, I tried a couple different brands/rw speed class micro sd chips in my xperia(s) and so far I can't find a 32 GB size that either xperia will reconize. I haven't tried a class 2 yet, maybe that's the problem. In any case I noted the x10 can't handle anything larger than 16 GB. If there is a 32 GB (the white pages say it handles 32 but doesn't show anything else) that works, I'd like to here from any user who has had such success, what brand, class/speed they have found that works.
